This augments %t which already resolves to the runtime directory root, and
should be useful for units that want to pass any of these paths in
command line arguments.
Example:
ExecStart=/usr/bin/mydaemon --datadir=%S/mydaemon
Why not expose a specifier resolving directly to the configured
state/runtime/cache/log dir? Three reasons:
1. Specifiers should be independent of configuration of the unit itself,
and StateDirectory= and friends are unit configuration. See
03fc9c723c and related work.
2. We permit multiple StateDirectory= values per unit, and it hence
wouldn't be clear which one is passed.
3. We already have %t for the runtime directory root, and we should
continue with the same scheme.
On some devices the display (LCD panel) is mounted non upright
in the device's casing, e.g. mounted upside-down or 90 degree rotated.
Document the expected ACCEL_MOUNT_MATRIX settings for such devices.
This fixes --read-only with --private-users. mkdir_userns_p may return
-EROFS if either mkdir or lchown fails; lchown failing is fine as the
mount point will just be overmounted, and if mkdir fails then the
following mount() will also fail (with ENOENT).
After previous output from systemd-shutdown indicated a bug, my attention
was drawn to redundant output lines. Did they indicate an anomaly?
It turns out to be an expected, harmless result of the current code. But
we don't have much justification to run such redundant operations. Let's
remove the confusing redundant message.
We can stop trying to remount a directory read-only once its mount entry
has successfully been changed to "ro". We can simply let the kernel keep
track of this for us. I don't bother to try and avoid re-parsing the
mountinfo. I appreciate snappy shutdowns, but this code is already
intricate and buggy enough (see issue 7131).
(Disclaimer: At least for the moment, you can't _rely_ on always seeing
suspicious output from systemd-shutdown. By default, you can expect the
kernel to truncate the log output of systemd-shutdown. Ick ick ick!
Because /dev/kmsg is rate-limited by default. Normally it prints a message
"X lines supressed", but we tend to shut down before the timer expires
in this case).
Before:
systemd-shutdown[1]: Remounting '/' read-only with options 'seclabel...
EXT4-fs (vda3): re-mounted. Opts: data=ordered
systemd-shutdown[1]: Remounting '/' read-only with options 'seclabel, ...
EXT4-fs (vda3): re-mounted. Opts: data=ordered
After:
systemd-shutdown[1]: Remounting '/' read-only with options 'seclabel, ...
EXT4-fs (vda3): re-mounted. Opts: data=ordered
I also tested with `systemctl reboot --force`, plus a loopback mount to
cause one of the umounts to fail initially. In this case another 2 lines
of output are removed (out of a larger number of lines).
This creates a second private resolve.conf file which lists the stub resolver
and the resolved acquired search domains.
This runtime file should be used as a symlink target for /etc/resolv.conf such
that non-nss based applications can resolve search domains.

When a user logs in, systemd-pam will wait for the user manager instance to
report readiness. We don't need to wait for all the jobs to finish, it
is enough if the basic startup is done and the user manager is responsive.
systemd --user will now send out a READY=1 notification when either of two
conditions becomes true:
- basic.target/start job is gone,
- the initial transaction is done.
Also fixes#2863.
The current code shifting an integer 1 failed for capabilities like
CAP_MAC_ADMIN (numerical value 33). This caused issues when specifying
them in the nspawn configuration file. Using an uint64_t 1 instead.
The similar code for processing the --capability command line option
was already correctly working.
The vast majority of touchpads are internal, so let's assume that any USB
touchpad is internal by default (exception: bluetooth) and manually mark the
ones that are external. That's a lot more future-proof than having to mark all
internal touchpads that use USB as internal - that number is only going to
increase.

kmod upstream uses /lib/modprobe.d which means we need to use rootprefix
instead of prefix for installing the modprobe configuration file as
otherwise split-usr systems are broken.

The assumption was that nothing changes in the final attempt. This
would be confusing if a filesystem with a process in uninterruptible
sleep suddenly became un-stuck for the final attempt, but we still give
up and don't try to e.g. unmount any parent mounts.
I don't know how possible that is. But the code will be easier to read
without an assumption that it does not attempt to justify.
When using strftime in arbitrary locales, we cannot really say how big the
buffer should be. Let's make the buffer "large", which will work fine pretty
much always, and just print n/a if the timestamp does not fit. strftime returns
0 if the buffer is too small and a NUL-terminated string otherwise, so we
can drop the size specifications in string formatting.

If linkLocalAddressing is disabled in for the interface still then
we look for ndisc configured or not in link_check_ready.
Link local is used automatic address configuration and neighbor discovery protocol.
If link local is disabled we should not configure ndisc.
