tmpfiles: if we get ENOENT when opening /proc/self/fd/, check if /proc is mounted
let's return ENOSYS in that case, to make things a bit less confusng.
Previously we'd just propagate ENOENT, which people might mistake as
applying to the object being modified rather than /proc/ just not being
there.
Let's return ENOSYS instead, i.e. an error clearly indicating that some
kernel API is not available. This hopefully should put people on a
better track.
Note that we only do the procfs check in the error path, which hopefully
means it's the less likely path.
We probably can add similar bits to more suitable codepaths dealing with
/proc/self/fd, but for now, let's pick to the ones noticed in #14745.
run: don't wait for start job to complete when running interactively anyway
Otherwise we'd not read the services input while waiting for the job to
wait, and there's no point in waiting for the job anyway if we wait for
the unit to stop ultimately.
ubsan complains that we add an offset to a NULL ptr here in some cases.
Which isn't really a bug though, since we only use it as the end
condition for a for loop, but we can still fix it...
core: add debug log when a job in the activation queue is not runnable
When a job is skipped due its dependencies not being ready, log
a debug message saying what is holding it back.
This was very useful with transient units timing out to figure
out where the problem was.

mkosi: Unify environment for unit tests
Some testcases in test-execute rely on existence of user groups with
certain gids. However, their existence is not universally granted [1].
Although the test could be skipped in their absence and give up testing
some code paths, different approach was chosen -- create dummy groups in
the testing image.
[1] See how systemd-sysusers allocates gids (e.g.
src/test/test-uid-range.c).

mkosi: Use distro-invariant rootprefix
Distributions may be build with various configs, e.g. customized
rootprefix. It'd be unmaintanable to have specific mkosi.build for each
supported distro. Hence, make the build script flexible yet distro
oblivious.
Remove the artifact files indicating test result (testok, failed, and
skipped) just before running the test so we always get the latest and
most relevant result instead of incorrectly consuming previous results.

network: change UseGateway= default to UseRoutes= setting
Anyone previously using the UseRoutes=false parameter expected their
dhcp4-provided gateway route to be ignored, as well. However, with
the introduction of the UseGateway= parameter, this is no longer true.
In order to keep backwards compatibility, this sets the UseGateway=
default value to whatever UseRoutes= has been set to.
test: drop Disk (Size|Free|Floor|Ceiling) fields prior comparing
The disk attributes can take some time to update on certain filesystems,
so let's strip them from inputs of both `homectl` and `userdbctl` before
comparing them to avoid unexpected fails.
Also, switch from `cmp` to `diff` to make a potential test fail a bit more
debuggable.
core: add log_get_max_level check optimization in log_unit_full
Just as log_full already does, check if the log level would result in
logging immediately in the macro in order to avoid doing
unnecessary work that adds up in hot spots.
log-control-api: add generic D-Bus interface for querying/setting log level/target
Let's define a new, generic bus interface that any daemon can implement
for querying/setting the log level.
We can turn this into something more powerful later on, but for now,
only expose three properties: the log level, log target and the syslog
identifier (with the former two being writable).
This is supposed to be generic, so that it can be implemented by 3rd
party daemons too, eventually.
core: automatically add udev dependency for units using RootImage=
We use udev to wait for /dev/loopX devices to be fully proped hence we
need an implicit ordering dependency on it, for RootImage= to work
reliably in early boot, too.

resolve: when the stub listener is disabled, symlink stub-resolv.conf to resolv.conf
When the stub listener is disabled, stub-resolv.conf is useless. Instead of
warning about this, let's just make stub-resolv.conf point to the private
resolv.conf file. (The original bug report asked for "mirroring", but I think
a symlink is nicer than a copy because it is easier to see that a redirection
was made.)
resolve: when writing of private resolv.confs fails, do not remove old copies
All callers ignore the return value.
This is almost entirely theoretical, since writing to /run is unlikely to
fail..., but the user is almost certainly better off keeping the old copy
around and having working dns resolution with an out-of-date dns server list
than having having a dangling /etc/resolv.conf symlink.
