This reworks the paragraph describing $SERVICE_RESULT into a table, and
adds two missing entries: "success" and "start-limit-hit".
These two entries are then also added to the table explaining the
$EXIT_CODE + $EXIT_STATUS variables.
Fixes: #6597
In this mode, we'll directly connect stdin/stdout/stderr of the invoked
service with whatever systemd-run itself is invoked on. This allows
inclusion of "systemd-run" commands in shell pipelines, as unlike
"--pty" this means EOF of stdin/stdout/stderr are propagated
independently.
If --pty and --pipe are combined systemd-run will automatically pick the
right choice for the context it is invoked in, i.e. --pty when invoked
on a TTY, and --pipe otherwise.
Now that we have ported nspawn's seccomp code to the generic code in
seccomp-util, let's extend it to support whitelisting and blacklisting
of specific additional syscalls.
This uses similar syntax as PID1's support for system call filtering,
but in contrast to that always implements a blacklist (and not a
whitelist), as we prepopulate the filter with a blacklist, and the
unit's system call filter logic does not come with anything
prepopulated.
(Later on we might actually want to invert the logic here, and
whitelist rather than blacklist things, but at this point let's not do
that. In case we switch this over later, the syscall add/remove logic of
this commit should be compatible conceptually.)
Fixes: #5163
Replaces: #5944
The values for StartLimitAction are defined in `man systemd.unit`.
Don't send people to `man systemd.service` just to find they need to look
back in `man systemd.unit` again :).
They’re counterparts to the existing set-log-level and set-log-target
verbs, simply printing the current value to stdout. This makes it
slightly easier to temporarily change the log level and/or target and
then restore the old value(s).
Add prefix delegation documentation covering IPv6PrefixDelegation=
setting in the Network section as well as all the parameters and
the IPv6PrefixDelegation and IPv6Prefix sections implemented so
far, including DNS= and DNSLifetimeSec= settings.
The pair is similar to remote-fs.target and remote-fs-pre.target. Any
cryptsetup devices which require network shall be ordered after
remote-cryptsetup-pre.target and before remote-cryptsetup.target.
They already were mostly ordered alphabetically, but some disorder
snuck in.
Also, fix formatting. Some options were described using "--" prefixes, which
looks like the text was just copied from crypttab(8).
Now we don't support tunnels to be created without a .network file
that is we need a interface index.
This work allows tunnel to be created without a ifindex.
Closes#6695
The irreversible job mode is required to ensure that shutdown is not
interrupted by the activation of a unit with a conflict.
We already used the correct job mode for `ctrl-alt-del.target`. But not
for `exit.target` (SIGINT of user manager). The SIGRT shutdown signals
also needed fixing.
Also change SIGRTMIN+0 to isolate default.target, instead of starting
it. The previous behaviour was documented. However there was no reason
given for it, nor can we provide one. The problem that isolate is too
aggressive anywhere outside of emergency.target (#2607) is orthogonal.
This feature is "accessible by different means and only really a safety
net"; it is confusing for it to differ from `systemctl default` without
explanation.
`AllowIsolate=yes` is retained on poweroff.target etc. for backwards
compatibility.
`sigpwr.target` is also an obvious candidate for linking to a shutdown
target. Unforunately it is also a possible hook for implementing some
logic like system V init did, reading `/etc/powerstatus`. If we switched
to starting `sigpwr.target` with REPLACE_IRREVERSIBLY, attempts to run
`systemctl shutdown` from it would fail, if they had not thought to set
`DefaultDependencies=no`. We had provided no examples for `sigpwr`, and
the whole idea is cruft to keep legacy people happy. For the moment, I
leave `sigpwr` alone, with no risk of disrupting anyone's
previously-working, half-working, or untested setup.
Fixes#6484. See also #6471
It's like Manager.PowerOff(), which does not start poweroff.target.
Instead, the dbus methods are used for `systemctl --force exit`
or `systemctl --force poweroff`. They shut down the system without
processing individual unit's ExecStop or TimeoutStopSec.
This new target is a passive unit, hence it is supposed to be pulled in
to the transaction by the service that wants to block login on the
console (e.g. text version of initial-setup). Now both getty and
serial-getty are ordered after this target.

The last sentence in the paragraph described the behaviour of `--global`. But "the last case" we listed was "only this boot", which does not match... This was the fifth case described, but there are only _four_ different option names. Fix it.
Add LockPersonality boolean to allow locking down personality(2)
system call so that the execution domain can't be changed.
This may be useful to improve security because odd emulations
may be poorly tested and source of vulnerabilities, while
system services shouldn't need any weird personalities.
This patch adds two new special character prefixes to ExecStart= and
friends, in addition to the existing "-", "@" and "+":
"!" → much like "+", except with a much reduced effect as it only
disables the actual setresuid()/setresgid()/setgroups() calls, but
leaves all other security features on, including namespace
options. This is very useful in combination with
RuntimeDirectory= or DynamicUser= and similar option, as a user
is still allocated and used for the runtime directory, but the
actual UID/GID dropping is left to the daemon process itself.
This should make RuntimeDirectory= a lot more useful for daemons
which insist on doing their own privilege dropping.
"!!" → Similar to "!", but on systems supporting ambient caps this
becomes a NOP. This makes it relatively straightforward to write
unit files that make use of ambient capabilities to let systemd
drop all privs while retaining compatibility with systems that
lack ambient caps, where priv dropping is the left to the daemon
codes themselves.
This is an alternative approach to #6564 and related PRs.
This new group lists all UID/GID credential changing syscalls (which are
quite a number these days). This will become particularly useful in a
later commit, which uses this group to optionally permit user credential
changing to daemons in case ambient capabilities are not available.
Currently if tmpfiles is run with force on symlink creation but there already
exists a directory at that location, the creation will fail. This change
updates the behavior to remove the directory with rm_fr and then attempts to
create the symlink again.
* Containers don't use serial-getty@console.service,
they use console-getty.service instead, and suppress
scanning for kernel or virtualizer consoles.
* Nowadays gettys are started on *all* configured kernel consoles.
* except for the line printer console, because that's not a tty.
(Seriously. Search CONFIG_LP_CONSOLE).
some run_target() calls were using params from custom_target()
example message:
WARNING: Passed invalid keyword argument "input". This will become a hard error in the future.
New way to call targets:
ninja man/man
ninja man/html
ninja man/update-man-rules
Without this requirement, if proxy-to-nginx.socket was down, and the sysadmin
were to do:
systemctl start proxy-to-nginx.service
then the service would come up without a configured socket, which doesn't make
sense. Normally this isn't how we expect a socket-activated service to start,
but it's possible for an admin to do this (if the .socket were already running,
the systemd-socket-proxyd process will start effectively idle). But the
.service shouldn't end up in a broken state if the .socket isn't already
listening.
Adding the explicit Requires: should ensure that an admin with this
configuration state can't accidentally break their system.
The long man page paragraph got it right: the tool is for escaping systemd unit
names, not just system unit names. Also fix the short man page paragraph
and the --help text.
Follow-up for 303608c1bc
rescue.target does not work well, and we don't have a suitable emergency
shell unit that can be started on existing systems right now. So let's just
remove the recommendation for now.
Fixes#6451.
Since busname units are only useful with kdbus, they weren't actively
used. This was dead code, only compile-tested. If busname units are
ever added back, it'll be cleaner to start from scratch (possibly reverting
parts of this patch).
This introduces {State,Cache,Log,Configuration}Directory= those are
similar to RuntimeDirectory=. They create the directories under
/var/lib, /var/cache/, /var/log, or /etc, respectively, with the mode
specified in {State,Cache,Log,Configuration}DirectoryMode=.
This also fixes#6391.
This has a long history; see see 5261ba9018
which originally introduced the behavior. Unfortunately that commit
doesn't include any rationale, but IIRC the basic issue is that
systemd wants to model the real mount state as units, and symlinks
make canonicalization much more difficult.
At the same time, on a RHEL6 system (upstart), one can make e.g. `/home` a
symlink, and things work as well as they always did; but one doesn't have
access to the sophistication of mount units (dependencies, introspection, etc.)
Supporting symlinks here will hence make it easier for people to do upgrades to
RHEL7 and beyond.
The `/home` as symlink case also appears prominently for OSTree; see
https://ostree.readthedocs.io/en/latest/manual/adapting-existing/
Further work has landed in the nspawn case for this; see e.g.
d944dc9553
A basic limitation with doing this in the fstab generator (and that I hit while
doing some testing) is that we obviously can't chase symlinks into mounts,
since the generator runs early before mounts. Or at least - doing so would
require multiple passes over the fstab data (as well as looking at existing
mount units), and potentially doing multi-phase generation. I'm not sure it's
worth doing that without a real world use case. For now, this will fix at least
the OSTree + `/home` <https://bugzilla.redhat.com/show_bug.cgi?id=1382873> case
mentioned above, and in general anyone who for whatever reason has symlinks in
their `/etc/fstab`.
When "bg" is specified for NFS mounts, and if the server is
not accessible, two behaviors are possible depending on networking
details.
If a definitive error is received, such a EHOSTUNREACH or ECONNREFUSED,
mount.nfs will fork and continue in the background, while /bin/mount
will report success.
If no definitive error is reported but the connection times out
instead, then the mount.nfs timeout will normally be longer than the
systemd.mount timeout, so mount.nfs will be killed by systemd.
In the first case the mount has appeared to succeed even though
it hasn't. This can be confusing. Also the background mount.nfs
will never get cleaned up, even if the mount unit is stopped.
In the second case, mount.nfs is killed early and so the mount will
not complete when the server comes back.
Neither of these are ideal.
This patch modifies the options when an NFS bg mount is detected to
force an "fg" mount, but retain the default "retry" time of 10000
minutes that applies to "bg" mounts.
It also imposes "nofail" behaviour and sets the TimeoutSec for the
mount to "infinity" so the retry= time is allowed to complete.
This provides near-identical behaviour to an NFS bg mount started directly
by "mount -a". The only difference is that systemd will not wait for
the first mount attempt, while "mount -a" will.
Fixes#6046
Fixes#295.
(We cannot add a comment to either of those files because they are documented
to "only support variable assignments", so it's better to add an explanation
in the man page instead.)
This makes `systemd-umount` or `systemd-mount -u` support unmounting
loop devices by the corresponding backing files, like
`systemd-mount --umount /tmp/foo.img /tmp/bar.img`
Fixes#6206.
Previously, only when --register=yes was set (the default) the invoked
container would get its own scope, created by machined on behalf of
nspawn. With this change if --register=no is set nspawn will still get
its own scope (which is a good thing, so that --slice= and --property=
take effect), but this is not done through machined but by registering a
scope unit directly in PID 1.
Summary:
--register=yes → allocate a new scope through machined (the default)
--register=yes --keep-unit → use the unit we are already running in an register with machined
--register=no → allocate a new scope directly, but no machined
--register=no --keep-unit → do not allocate nor register anything
Fixes: #5823
This makes systemd-umount (or systemd-mount -u) supports multiple arguments
which can be path, device, or fstab style node name, like
`systemd-umount /path/to/umount /dev/sda1 UUID=xxxxxx-xxxx LABEL=xxxxx`.
C.f. https://github.com/systemd/systemd/pull/5235#issuecomment-277731314.
This also alters the documentation to recommend memfds rather than /run
for serializing state across reboots. That's because /run doesn't
actually have the same lifecycle as the fd store, as it is cleared out
on restarts.
Fixes: #5606
This work allows to configure device port:

The escaping rules are a POSIX proposal, and are described in
http://austingroupbugs.net/view.php?id=249. There's a lot of back-and-forth on
the details of escaping of control characters, but we'll be only using a small
subset of the syntax that is common to all proposals and is widely supported.
Unfortunately dash and fish and maybe some other shells do not support it (see
the man page patch for a list).
This allows environment variables to be safely exported using show-environment
and imported into the shell. Shells which do not support this syntax will have
to do something like
export $(systemctl show-environment|grep -v '=\$')
or whatever is appropriate in their case. I think csh and fish do not support
the A=B syntax anyway, so the change is moot for them.
Fixes#5536.
v2:
- also escape newlines (which currently disallowed in shell values, so this
doesn't really matter), and tabs (as $'\t'), and ! (as $'!'). This way quoted
output can be included directly in both interactive and noninteractive bash.
Make sure to only apply the O_NONBLOCK flag to the fds passed via socket
activation.
Previously the flag was also applied to the fds which came from the fd store
but this was incorrect since services, after being restarted, expect that these
passed fds have their flags unchanged and can be reused as before.
The documentation was a bit unclear about this so clarify it.
The -ENOMEDIUM return value was introduced in v232-1001-g2977724b09,
('core: make hybrid cgroup unified mode keep compat /sys/fs/cgroup/systemd hierarchy'),
and would be returned by cg_pid_get_path_shifted(), but the documented and
expected return value is -ENODATA. Let's just catch ENXIO/ENOMEDIUM and translate
it to ENODATA in all cases.
Complements 171f8f591f, fixes#6012.
this patch makes it possible to configure a vlan aware bridge without the
PVID. To configure no PVID set DefaultPVID=none in the [BridgeVLAN] section.

This adds two options that are useful for user units. In particular, it
is useful to check ConditionUser=!0 to not start for the root user.
Closes: #5187
DHCP responses could include static routes, but unfortunately not an
option to tell what scope to use. So it's important that the client sets
it properly.
This mimics what the `ip route add` command does when adding a static
route without an explicit scope:
* If the destination IP is on the local host, use scope `host`
* Otherwise if the gateway IP is null (direct route), use scope `link`
* If anything else, use the current default `global`.
Fixes#5979.
test-login.c is largely rewritten to use _cleanup_ and give more meaningful
messages (function names are used instead of creative terms like "active
session", so that when something unexpected is returned, it's much easier to
see what function is responsible).
The monitoring part is only activated if '-m' is passed on the command line.
It runs against the information from /run/systemd/ in the live system, but that
should be OK: logind/sd-login interface is supposed to be stable and both
backwards and forwards compatible.
If not running in a login session, some tests are skipped.
Those two changes together mean that it's possible to run test-login in the
test suite.
Tests for sd_pid_get_{unit,user_unit,slice} are added.
sd_seat_get_sessions returns two arrays, that in principle should always match:
the session names and corresponding uids. The second array could be shorter only
if parsing or uid conversion fails. But in that case there is no way to tell
*which* uid is wrong, so they are *all* useless. It's better to simplify things and
just return an error if parsing fails.
The example for LD_LIBRARY_PATH in the environment.d man page is wrong.
When setting LD_LIBRARY_PATH, the new directory usually needs to be at
the front so it overrides old directories.
In the example, the colon delimiter is correctly prepended to the front, but
the actual new path is erroneously appended to the end.
This commit moves it to the front where it belongs.
Also updates the documentation and adds a mention of ppc64 support
which was enabled by #5325.
Tested on Debian mipsel and mips64el. The other 4 mips architectures
should have an identical user <-> kernel ABI to one of the 2 tested
systems.
Using conf.set() with a boolean argument does the right thing:
either #ifdef or #undef. This means that conf.set can be used unconditionally.
Previously I used '1' as the placeholder value, and that needs to be changed to
'true' for consistency (under meson 1 cannot be used in boolean context). All
checks need to be adjusted.
The symlinks should be created in the build directory in two cases: when
configuration specifies -Dhtml=true, or when ninja html target is built.
Normally install : {true,false} is used to decide if a target should be built,
but in this case, we cannot use install : true, because, as described in
488477d101, that results in the target file being copied into the
installation directory instead of a symlink. So we need a work-around. To
achieve the first end, the commands to create the symlinks are added as
dependencies of the command to create the html page. To the second end, they
are added as dependencies of the html target.
Follow-up for 488477d101 and 064d9ef0d7.
This adds two somewhat independent rules:
1. to create symlinks to html pages in the build directory
2. to create symlinks in the installation directory
The second part needs to be coded separately, because telling meson to install
the symlinks created in step 1. results in a copy of the target, instead of a
symlink. So step 2. needs to ignore the result of 1. and create the symlink again.
Fixes#5863.
This is useful on systems like NixOS, where python3 is not in
/usr/bin/python3 as well as for people using alternative ways to
install python such as virtualenv/pyenv.
Unit.JobTimeoutSec starts when a job is enqueued in a transaction. The
introduced distinct Unit.JobRunningTimeoutSec starts only when the job starts
running (e.g. it groups all Exec* commands of a service or spans waiting for a
device period.)
Unit.JobRunningTimeoutSec is intended to be used by default instead of
Unit.JobTimeoutSec for device units where such behavior causes less confusion
(consider a job for a _netdev mount device, with this change the timeout will
start ticking only after the network is ready).
In order to verify a pulled container or disk image, importd only supports
SHA256SUMS files with the detached signature in SHA256SUMS.gpg.
SUSE is using an inline signed file with the name of the image itself and the
suffix .sha256 instead.
This commit adds support for this type of signature files.
It is first attempted to pull the .sha256 file.
If this fails with error 404, the SHA256SUMS and SHA256SUMS.gpg files are
pulled and used for verification.
The indentation for emacs'es meson-mode is added .dir-locals.
All files are reindented automatically, using the lasest meson-mode from git.
Indentation should now be fairly consistent.
This doesn't feel as natural, but is more consistent with the boolean options
which require true/false, and allows setting of options without knowing of
which type the option is.
This provides functionality similar to the ./configure --disable-manpages
switch. Man pages are built by default (if xsltproc is found), html pages
are not. Those default can be changed with -Dman=no, -Dhtml=yes/auto.
It is still possible to build one or the either, even if not configured, with
ninja-build man/man and ninja-build man/html.
v2:
- obey conditionals in index/directives list
This is a bit bare-bones, but should work for now. Maybe in the future we'll
have a way to make meson generate it for us, without specifying all the names
by hand.
It's crucial that we can build systemd using VS2010!
... er, wait, no, that's not the official reason. We need to shed old systems
by requring python 3! Oh, no, it's something else. Maybe we need to throw out
345 years of knowlege accumulated in autotools? Whatever, this new thing is
cool and shiny, let's use it.
This is not complete, I'm throwing it out here for your amusement and critique.
- rules for sd-boot are missing. Those might be quite complicated.
- rules for tests are missing too. Those are probably quite simple and
repetitive, but there's lots of them.
- it's likely that I didn't get all the conditions right, I only tested "full"
compilation where most deps are provided and nothing is disabled.
- busname.target and all .busname units are skipped on purpose.
Otherwise, installation into $DESTDIR has the same list of files and the
autoconf install, except for .la files.
It'd be great if people had a careful look at all the library linking options.
I added stuff until things compiled, and in the end there's much less linking
then in the old system. But it seems that there's still a lot of unnecessary
deps.
meson has a `shared_module` statement, which sounds like something appropriate
for our nss and pam modules. Unfortunately, I couldn't get it to work. For the
nss modules, we need an .so version of '2', but `shared_module` disallows the
version argument. For the pam module, it also didn't work, I forgot the reason.
The handling of .m4 and .in and .m4.in files is rather awkward. It's likely
that this could be simplified. If make support is ever dropped, I think it'd
make sense to switch to a different templating system so that two different
languages and not required, which would make everything simpler yet.
v2:
- use get_pkgconfig_variable
- use sh not bash
- use add_project_arguments
v3:
- drop required:true and fix progs/prog typo
v4:
- use find_library('bz2')
- add TTY_GID definition
- define __SANE_USERSPACE_TYPES__
- use join_paths(prefix, ...) is used on all paths to make them all absolute
v5:
- replace all declare_dependency's with []
- add more conf.get guards around optional components
v6:
- drop -pipe, -Wall which are the default in meson
- use compiler.has_function() and compiler.has_header_symbol instead of the
hand-rolled checks.
- fix duplication in 'liblibsystemd' library name
- use the right .sym file for pam_systemd
- rename 'compiler' to 'cc': shorter, and more idiomatic.
v7:
- use ENABLE_ENVIRONMENT_D not HAVE_ENVIRONMENT_D
- rename prefix to prefixdir, rootprefix to rootprefixdir
("prefix" is too common of a name and too easy to overwrite by mistake)
- wrap more stuff with conf.get('ENABLE...') == 1
- use rootprefix=='/' and rootbindir as install_dir, to fix paths under
split-usr==true.
v8:
- use .split() also for src/coredump. Now everything is consistent ;)
- add rootlibdir option and use it on the libraries that require it
v9:
- indentation
v10:
- fix check for qrencode and libaudit
v11:
- unify handling of executable paths, provide options for all progs
This makes the meson build behave slightly differently than the
autoconf-based one, because we always first try to find the executable in the
filesystem, and fall back to the default. I think different handling of
loadkeys, setfont, and telinit was just a historical accident.
In addition to checking in $PATH, also check /usr/sbin/, /sbin for programs.
In Fedora $PATH includes /usr/sbin, (and /sbin is is a symlink to /usr/sbin),
but in Debian, those directories are not included in the path.
C.f. https://github.com/mesonbuild/meson/issues/1576.
- call all the options 'xxx-path' for clarity.
- sort man/rules/meson.build properly so it's stable
--new-id works because it’s an unambiguous prefix, but the full option
name is --new-id128.
(#5381 did the same in one other manpage, but I didn’t check for other
manpages using the abbreviated version back then.)
This work based on Tom's original patch
teg@1312172
By setting GatewayOnlink=yes, the kernel will assume that the gateway is onlink
even if there is no route to it.
Resolves issue #1283.
Allow setting bridge port priority in the Bridge section of the network file,
similar to e.g. port path cost setting.
Set the default to an invalid value of 128, and only set the port priority when
it's not 128. Unlike e.g. path cost, zero is a valid priority value.
Add a networkd-test.py to check that bridge port priority is correctly set.
Incidently, fix bridge port cost type and document valid ranges.
So far, all sections of the systemd.special(7) man page used
<varlistentry> for listing the targets, with one exception: the
"Special Passive User Units" one. Let's clean this up and use the same
formatting everywhere.
Per man:file-hierarchy(7), /lib is just a compatibility symlink; the
other manpages also refer to /usr/lib.

This updates the man page for the changes introduced in 1d84ad9445.
"=" is kep if the option is predominantly used with an argument, and dropped
otherwise.
v2:
- update also description of log_color
- drop '=' in all cases where it is optional
(previous rule of dropping it only in some cases was just too arbitrary.)
Sometimes it's useful to provide a default value during an environment
expansion, if the environment variable isn't already set.
For instance $XDG_DATA_DIRS is suppose to default to:
/usr/local/share/:/usr/share/
if it's not yet set. That means callers wishing to augment
XDG_DATA_DIRS need to manually add those two values.
This commit changes replace_env to support the following shell
compatible default value syntax:
XDG_DATA_DIRS=/foo:${XDG_DATA_DIRS:-/usr/local/share/:/usr/share}
Likewise, it's useful to provide an alternate value during an
environment expansion, if the environment variable isn't already set.
For instance, $LD_LIBRARY_PATH will inadvertently search the current
working directory if it starts or ends with a colon, so the following
is usually wrong:
LD_LIBRARY_PATH=/foo/lib:${LD_LIBRARY_PATH}
To address that, this changes replace_env to support the following
shell compatible alternate value syntax:
LD_LIBRARY_PATH=/foo/lib${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}
[zj: gate the new syntax under REPLACE_ENV_ALLOW_EXTENDED switch, so
existing callers are not modified.]
In the future we might want to allow additional syntax (for example
"unset VAR". But let's check that the data we're getting does not contain
anything unexpected.
(Only in environment.d files.)
We have only basic compatibility with shell syntax, but specifying variables
without using braces is probably more common, and I think a lot of people would
be surprised if this didn't work.
Add support for /etc/environment and document the changes to the user manager
to automatically import environment *.conf files from:
~/.config/environment.d/
/etc/environment.d/
/run/environment.d/
/usr/local/lib/environment.d/
/usr/lib/environment.d/
/etc/environment
Why the strange name: the prefix is necessary to follow our own advice that
environment generators should have numerical prefixes. I also put -d- in the
name because otherwise the name was very easy to mistake with
systemd.environment-generator. This additional letter clarifies that this
on special generator that supports environment.d files.
v2:
- add example files to EXTRA_DIST
v3:
- rework for the new scheme where nothing is written to disk
v4:
- use separate dirs for system and user env generators
As the kernel won't map the UIDs this is simply not safe, and hence we
should generate a clean error and refuse it.
We can restore this feature later should a "shiftfs" become available in
the kernel.
This changes the file copy logic of machined to set the UID/GID of all
copied files to 0 if the host and container do not share the same user
namespace.
Fixes: #4078
This breaks again, this time for setups where Qemu is not reported via DMI for whatever
reason. So swap order of cpuid and dmi again, but properly detect oracle.
See issue #5318.
Embedding sd_id128_t's in constant strings was rather cumbersome. We had
SD_ID128_CONST_STR which returned a const char[], but it had two problems:
- it wasn't possible to statically concatanate this array with a normal string
- gcc wasn't really able to optimize this, and generated code to perform the
"conversion" at runtime.
Because of this, even our own code in coredumpctl wasn't using
SD_ID128_CONST_STR.
Add a new macro to generate a constant string: SD_ID128_MAKE_STR.
It is not as elegant as SD_ID128_CONST_STR, because it requires a repetition
of the numbers, but in practice it is more convenient to use, and allows gcc
to generate smarter code:
$ size .libs/systemd{,-logind,-journald}{.old,}
text data bss dec hex filename
1265204 149564 4808 1419576 15a938 .libs/systemd.old

146391 4984 34 151409 24f71 .libs/systemd-journald
It is also much easier to check if a certain binary uses a certain MESSAGE_ID:
$ strings .libs/systemd.old|grep MESSAGE_ID
MESSAGE_ID=%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x

In commit 050e65a we swapped order of detect_vm_{cpuid,dmi}(). That
fixed Virtualbox but broke qemu with kvm, which is expected to return
'kvm'. So check for qemu/kvm first, then DMI, CPUID last.
This fixes#5318.

Currently fstab entries with 'nofail' option are mounted
asynchronously and there is no way how to specify dependencies
between such fstab entry and another units. It means that
users are forced to write additional dependency units manually.
The patch introduces new systemd fstab options:
x-systemd.before=<PATH>
x-systemd.after=<PATH>
- to specify another mount dependency (PATH is translated to unit name)
x-systemd.before=<UNIT>
x-systemd.after=<UNIT>
- to specify arbitrary UNIT dependency
For example mount where A should be mounted before local-fs.target unit:
/dev/sdb1 /mnt/test/A none nofail,x-systemd.before=local-fs.target
