I don't see where it would ever be a good thing that file copies done
via tmpfiles.d/ C lines cause the tmpfiles operation to fail if their
source happens to be missing. It's a problem if we can't set up the
destination properly (which is the job of systemd-tmpfiles after all),
but if the source is simply missing (NB: setting up the source is the job of
of the rules writer) this shouldn't be a problem.
This is useful for copying stuff into place if it happens to exist. For
example, if systemd-stub passes additional data into the initrd's
/.extra/ directory, we can copy it into a better place (e.g. /run/) with
this, where it will survive the initrd→host transition.
This mirrors behaviour of the recently added "^" line modifier which may
be used source "w" lines from credentials – there two the behaviour is
to simply skip the line if the source is missing.
getopt allows non-ambiguous abbreviations, so backwards-compat is maintained, and
people can use --kill-who (or even shorter abbreviations). English is flexible,
so in common speach people would use both forms, even if "whom" is technically
more correct. The advantage of using the longer form in the code is that we
effectively allow both forms, so we stop punishing people who DTGCT¹, but still
allow people to use the spoken form if they prefer.
1. Do the gramatically correct thing
When a service unit Requires= a socket, and the socket is restarted while the
service is in state=activating, the propagated restart is being discarded. This
is contrary to the documentation for Requires=, which states "this unit will be
stopped (or restarted) if one of the other units is explicitly stopped (or
restarted)".
Otherwise we might never hit the trigger limit and wait indefinitely.
Found when trying to run the test on an EC2 xen machine without a nested
virt in CentOS CI (in preparations for some ... unforseseen consequences).
/bin/sh as a shell is punishing. There is no good reason to make
the occasional root login unpleasant.
Since /bin/sh is usually /bin/bash in compat mode, i.e. if one is
available, the other will be too, /bin/bash is almost as good as a default.
But to avoid a regression in the situation where /bin/bash (or
DEFAULT_USER_SHELL) is not installed, we check with access() and fall back
to /bin/sh. This should make this change in behaviour less risky.
(FWIW, e.g. Fedora/RHEL use /bin/bash as default for root.)
This is a follow-up of sorts for 53350c7bba,
which added the default-user-shell option, but most likely with the idea
of using /bin/bash less ;)
Fixes#24369.
When a service is triggered by a path unit, pass the
path unit name and the path that triggered it via env vars
to the spawned processes.
Note that this is best-effort, as there might be many triggers
at the same time, but we only get woken up by one.
Otherwise we might start writing to one of its partition before the
respective node is created under /dev, resulting in... interesting
stuff.
Resolves: #24390
The knot.service on Ubuntu Jammy loads an env file which we didn't
install, causing the service to fail:
```
knot.service: Will spawn child (service_enter_start_pre): /usr/sbin/knotc
knot.service: Failed to load environment files: No such file or directory
knot.service: Failed to run 'start-pre' task: No such file or directory
knot.service: Failed with result 'resources'.
knot.service: Service will not restart (restart setting)
```
Previously, the test would rely on the fact that systemd-hwdb would
follow symlinks outside of the --root= hierarchy. That's a bug however,
and systemd-hwdb shouldn't do that. Hence let's remove the fact that the
test relies on it, so that we can then fix systemd-hwdb (specifically:
conf_files_list()) accordingly.
In 'udevadm lock' the device /dev/loopX is locked instead of
/dev/loopXp1. Hence, 'udevadm wait' should wait for /dev/loopX.
For some reasons, the kernel sometimes does not emit uevent for
partitions, and 'udevadm wait' for partitions may fail.
Fixes#24360.
Some tests (like TEST-02) set a multiline string to $KERNEL_APPEND
(which is a valid thing to do), unfortunately we'd use only the first
line of it and throw the rest away, e.g:
```
$ printf "%s" "$x"
hello
this is a multiline
kernel command line
$ read -ra out <<< "$x"
$ printf "%s" "${out[@]}"
hello
```
Let's use readarray/mapfile instead to avoid this:
```
$ readarray out <<< "$x"
$ printf "%s" "${out[@]}"
hello
this is a multiline
kernel command line
```
We can't get any FS meta-data from a suspended device. Hence defer
making any plugged/unplugged decisions, i.e. we just import whatever was
previous state and skip processing all other rules.
Thanks Lennart Poettering <lennart@poettering.net> for suggesting this
solution.
libdevmapper/device mapper driver can return semi-random failures when
opening verity devices, and we have fallback code to deal with it.
But the test was not expecting the fallback path, so it became unreliable.

While I had tested that a symlink to /dev/null works to "mask" a sysext
I must have gotten something wrong and thus the instructions in
519c2f0d6b don't work. What works,
at least at the moment, is to instead have an empty directory with the
extension name under /etc/extensions/.
Correct the info in the man page and add a test for it.
When an extension image has binaries they should match the host
architecture. Currently there is no way to specify this requirement.
Introduce an ARCHITECTURE field in the extension's release file that
may be set to prevent loading on the wrong host architecture.
Since this new field is introduced late, we don't want to make
specifying it mandatory as it would break existing sysext images.
See https://github.com/systemd/systemd/issues/24061
A sysext image that merely contains static binaries has no dependency
on the host distribution and should be able to be used anywhere.
Support the special '_any' value for the ID field in the extension to
opt-out of ID and VERSION_ID/SYSEXT_LEVEL matching.
