278c13431b github: ask for arch+kernel in bug report form
Quite often we see kernel and arch specific issues, let's ask for the
version right-away when people file the issue.

Other tweaks.

4b6f9b202e sysusers: emit warnings about login.defs overrides on first user or group creation
*** Running /home/zbyszek/src/systemd-work/test/test-sysusers/test-14.input (with login.defs symlinked)
login.defs specifies UID allocation range 401–555 that is different than the built-in defaults (201–998)
login.defs specifies GID allocation range 405–666 that is different than the built-in defaults (201–990)

a3709e3709 tests: when creating temp dirs, include test name in path
This makes it easier to figure out which directory we want to look at
when tests fail, and also which test left behind a directory when it
shouldn't.

aa25270cb2 sysusers: look at login.defs when setting the default range to allocate users
Also, even if login.defs are not present, don't start allocating at 1, but at
SYSTEM_UID_MIN.

Fixes #9769.

The test is adjusted. Actually, it was busted before, because sysusers would
never use SYSTEM_GID_MIN, so if SYSTEM_GID_MIN was different than
SYSTEM_UID_MIN, the tests would fail. On all "normal" systems the two are
equal, so we didn't notice. Since sysusers now always uses the minimum of the
two, we only need to substitute one value.

044df624aa test-sysusers: fix how paths are calculated
We were looking at ${f%.*}, i.e. the $f with any suffix starting with a dot removed.
This worked fine for paths like /some/path/test-11.input. It also worked
for paths like /some/path/inline (there were no dots, so we got $f back unscathed).
But in the ubuntu CI the package is built in a temporary directory like
/tmp/autopkgtest-lxc.nnnfqb26/downtmp/build.UfW/ (yes, it has a dot, even two.).
That still worked for the first case, but in the second case we truncated things
after the first dot, and we would try to get
/tmp/autopkgtest-lxc.nnnfqb26/downtmp/build and try to load
/tmp/autopkgtest-lxc.nnnfqb26/downtmp/build.expected-password, which obviously
didn't work as expected. To avoid this issue, do the suffix removal only when
we know that there really is a suffix.

A second minor issue was that we would try to copy $1.expected-*, and sometimes
$1 would be given, and sometimes not. Effectively we were relying on there
not being any files matching .expected-*. There weren't any such files, but let's
avoid this ugliness and always pass $1.

fc1a5d1a70 Also parse the minimum uid/gid values
We don't (and shouldn't I think) look at them when determining the type of the
user, but they should be used during user/group allocation. (For example, an
admin may specify SYS_UID_MIN==200 to allow statically numbered users that are
shared with other systems in the range 1–199.)

53393c894d Look at /etc/login.defs for the system_max_[ug]id values
It makes little sense to make the boundary between systemd and user guids
configurable. Nevertheless, a completely fixed compile-time define is not
enough in two scenarios:
- the systemd_uid_max boundary has moved over time. The default used to be
  500 for a long time. Systems which are upgraded over time might have users
  in the wrong range, but changing existing systems is complicated and
  expensive (offline disks, backups, remote systems, read-only media, etc.)
- systems are used in a heterogenous enviornment, where some vendors pick
  one value and others another.
So let's make this boundary overridable using /etc/login.defs.

Fixes #3855, #10184.

ef9bddb799 log: normalize log target condition check
THis doesn't change the condition's logic at all, but is an attempt to
make things a bit more readable: instead of checking log_target !=
LOG_TARGET_AUTO let's actually list the targets where we want to
consider journal/syslog/kmsg, to make things a bit less confusing. After
all the message here is not to avoid them if LOG_TARGET_AUTO is set, but
to definitely do them in the other cases.

d1f6e01e47 homed: explicitly deactivate all home directories on shutdown
Let's explicitly deactivate all home dirs on shutdown, in order to
properly synchronizing unmounting and avoiding blocking devices.

Previously, we'd rely on automatic deactivation when home directories
become unused. However, that scheme is asynchronous, and ongoing
deactviations might conflicts with attempts to unmount /home. Let's fix
that by providing an explicit service systemd-homed-activate.service
whose only job is to have a ExecStop= line that explicitly deactivates
all home directories on shutdown. This service can the be ordered after
home.mount and similar, ensuring that we'll first deactivate all homes
before deactivating /home itself during shutdown.

This is kept separate from systemd-homed.service so that it is possible
to restart systemd-homed.service without deactivating all home
directories.

b3ffa2b5f3 resolved: turn off that a search domain is derived from the host's fqdn
If the hostname of a system is set to an fqdn, glibc traditionally
derives a search domain from it if none is explicitly configured.

This is a bit weird, and we currently don't do that in our own search
path logic.

Following #17193 let's turn this behaviour off for now.

Yes, this has a slight chance of pissing people off who think this
behaviour is good. If this is indeed an issue, we can revisit the issue
but in that case if we readd the concept we should do it properly:
derive the search domain from the fqdn in our codebase too and report it
in resolvectl, and in our generated stub files. But I have the suspicion
most people who set the hostname to an fqdn aren#t even aware of this
behaviour nor want it, so let's wait until people complain.

We should avoid duplicating lengthy description of very similar concepts.
--root-hash-sig follows the same semantics as RootHashSig=, so just refer
the reader to the other man page. --root-hash doesn't implement the same
features as RootHash=, so we can't fully replace the description, but let's
give the user a hint to look at the other man page too.

7fd897c51c man: explain why TZ=: is used
Also, reword the description a bit. "As a string" is meaningless in the context
of commandline arguments, where evyrything is a string. This is not a
strongly-typed programming language where 5 is a number but "5" is something
completely different. Here both 5 and "5" are indistinguishable. The original
text was trying to say that a location name should be given and not a number,
so say "time zone location name".

foreign → someone/something else manages /etc/resolv.conf,

missing → /etc/resolv.conf is missing altogether

stub/static/uplink → the file is managed by resolved, with the
