Since 7c764d4 we bind mount certain directories during switch root
instead of moving the mount directly, and for /run we do this without
MS_REC. This, unfortunately, leaves all mounts under /run behind
in the old root, which breaks certain use cases.
See: https://github.com/systemd/systemd/issues/28452
As it says on the tin, configures the unit to survive a soft reboot.
Currently all the following options have to be set by hand:
Conflicts=reboot.target kexec.target poweroff.target halt.target
Before=reboot.target kexec.target poweroff.target halt.target
After=sysinit.target basic.target
DefaultDependencies=no
IgnoreOnIsolate=yes
This is not very user friendly. If new default dependencies are added,
or new shutdown/reboot types, they also have to be added manually.
The new option is much simpler, easy to find, and does the right thing
by default.
This fixes the test failure when invoked by a user.

This also makes the test uses fallback paths.
Follow-up for b50aadaff2.
This fixes regression introduced in 5a0c810462 with which all requests
for link properties ended up with EINVAL as we kept hitting
the signature_is_single() assert in sd_bus_get_property().
Currently for portable services we automatically add a bind mount
os-release -> /run/host/os-release. This becomes problematic for the
soft-reboot case, as it's likely that portable services will be configured
to survive it, and thus would forever keep a reference to the old host's
os-release, which would be a problem because it becomes outdated, and also
it stops the old rootfs from being garbage collected.
Create a copy when the manager starts under /run/systemd/propagate instead,
and bind mount that for all services using RootDirectory=/RootImage=, so
that on soft-reboot the content gets updated (without creating a new file,
so the existing bind mounts will see the new content too).
This expands the /run/host/os-release protocol to more services, but I
think that's a nice thing to have too.
Closes https://github.com/systemd/systemd/issues/28023
We create the udevadm -> systemd-udevd symlink during the install phase,
so it doesn't exist in the just compiled tree. This worked in CI since
the symlink is manually created there post-build.
Minor change, to adjust mode of /tmp/passphrase and /tmp/password test files to
avoid repeated warning logs that each file "...has 0644 mode that is too
permissive, please adjust the ownership and access mode."
In etc_hosts_lookup_by_address(), make sure the canonical name of the given
address is returned first in the list of names that address resolves to.
Resolves: #25088
