Break out the write logic into a separate function and simply use it as
a callback to glob_item.
This allows users to consolidate writes to sysfs with multiple similar
pathnames, e.g.
w /sys/class/block/sd[a-z]/queue/read_ahead_kb - - - - 1024
This splits the JSON output mode into different modes: json and
json-pretty. The former printing one entry per line, the latter showing
JSON objects nicely indented and in multiple lines to make it easier to
read for humans.
After talking to the cgroup kernel folks at LPC we came to the
conclusion that it is probably a good idea to mount all CPU related
resp. all network related cgroup controllers together, both because they
are good defaults for admins and because this might prepare
for eventual kernel cleanups where the ability to mount them separately
is removed.
In some cases, like wrong configuration, restarting after error
does not help, so administrator can specify statuses by RestartPreventExitStatus
which will not cause restart of a service.
Sometimes you have non-standart exit status, so this can be specified
by SuccessfulExitStatus.
- don't use pivot_root() anymore, just reuse root hierarchy
- first create all mounts, then mark them read-only so that we get the
right behaviour when people want writable mounts inside of
read-only mounts
- don't pass invalid combinations of MS_ constants to the kernel
This is useful e.g. if the keyfile is a raw device, where only parts of it
should be read. It is typically used whenever the keyfile-offset= option is
specified.

We want to keep things uniform, and hence treat udevd's man page like
any other in the repo. What matters is how users primarily interface
with a service, and that is not the binary path in /usr/lib/systemd but
the service name.
This reverts commit 6c1f3ba54a.
Instead of making systemd-udevd a so-link to systemd-udevd.service,
ship the real page as systemd-udevd to integrate better with distros
where udevd might be run standalone.
This should address TODO item "new dependency type to "group" services
in a target". Semantic of new dependency is as follows. Once configured
it creates dependency which will cause that all dependent units get
stopped if unit they all depend on is stopped or restarted. Usual use
case would be configuring PartOf=some.target in template unit file
and WantedBy=some.target in [Install] section and enabling desired
number of instances. In this case starting one instance won't pull in
target but stopping or starting target(in case of WantedBy is properly
configured) will cause stop/start of all instances.
systemd --version mirrors systemctl --version:
$ ./systemd --version
systemd 186
other
+PAM +LIBWRAP +AUDIT +SELINUX +IMA +SYSVINIT -LIBCRYPTSETUP
This information can be retrieved by other means (systemctl, etc.),
but it's easier for a newbie if 'systemd --version' says something
useful. And 'systemd --help' is already there, so let's complement
that with '--version'.
Previously, when the main data hash table grows too full the performance
simply started to decrease drastically. Instead, now simply rotate to a
new journal file as the hash table gets to full, so that we can start
with a new fresh empty hash table.
These printf specifiers allow us to refer to $HOME and $USER
in unit files. These are particularly helpful in instanced
units that have "User=" set, and in systemd --user domains.
The specifiers will return the pw_name and pw_dir fields
if the unit file has a User= field.
If the unit file does not have a User= field, the value
substituted is either $USER or $HOME from the environment,
or, if unset, the values from pw_name or pw_dir.
This patch is somewhat after Ran Benita's original patch,
which didn't get merged. I've split up the 2 specifiers
and extended them to do what is logically expected from
these specifiers.
Note that expansion is done at `start` time, not after
the units are parsed. Using `systemctl show` will just
show the specifiers.
all other dependencies are in 3rd person. Change BindTo= accordingly to
BindsTo=.
Of course, the dependency is widely used, hence we parse the old name
too for compatibility.
we now can take multiple matches, and they will apply as AND if they
apply to different fields and OR if they apply to the same fields. Also,
terms of this kind can be combined with an overreaching OR.
There's now sd_journal_new_directory() for watching specific journal
directories. This is exposed in journalctl -D.
sd_journal_wait() and sd_journal_process() now return whether changes in
the journal are invalidating or just appending.
We now create inotify kernel watches only when we actually need them
E.g. systemctl --all -t masked gives the list of masked units.
The -t/--type option is reused. This is possible because unit types
and unit load states are called differently, so it is possible to
distinguish what the user meant. Using the same option also means that
the interface is user for the user: less options to remember.
This is useful if your keyfile is a block device, and you want to
use a specific part of it, such as an area between the MBR and the
first partition.
This feature is documented in the Arch wiki[0], and has been supported
by the Arch initscripts, so would be nice to get this into systemd.
This requires libcryptsetup >= 1.4.2 (released 12.4.2012).

This naming convention is more inline with other systemd daemon
unit names (systemd-logind.service, systemd-localed.service etc)
The companion .socket units have also been renamed, however the
-trigger and -settle units keep their current name as these are
not directly related to daemon process itself.
This replaces the symlink based dependency by an explicit one in the
unit file so that we avoid the dangling symlink when no display manager
is installed.
The rule is that units that encapsulate our own code are prefixed with
"systemd-". Since the fsck units invoke our own code, hence add the
missing prefix. Since a long long time the fsck units didn't invoke the
naked fsck binaries anymore, and it is unlikely that this well ever
change. On the opposite: the code in systemd-fsck will probably get more
complex over time to handle fsck progress to plymouth forwarding.
Same for quotacheck (but not quotaon!)
Names= is a source of errors, simply because alias names specified like
this only become relevant after a unit has been loaded but cannot be
used to load a unit.
Let's get rid of the confusion and drop this field. To establish alias
names peope should use symlinks, which have the the benefit of being
useful as key to load a unit, even though they are not taken into
account if unit names are listed but they haven't been explicitly
referenced before.
