There's a race condition in the sysuser test where it may try to read
entries from the journal before they are available. Fix it by adding a
`journalctl --sync` call.

Failing after a single check leads to extra sleeps scattered through
test cases, and can also lead to false failures. Instead perform a
recheck for a number of seconds until the state matches, and fail only
if the timeout is exceeded.
This allows removing all the manual sleeps in the testcases.
We wait for "basic.target" being reached in the user instance anyway
before allowing the user's session to start, hence doing such a wait is
unnecessary, since that would just mean we'd wait for "default.target"
on top of "basic.target", but we shouldn#t need anything of that...
Hence, let's simplify this, reduce explicit sync points.
The name is not as universal as we want, still, hence let's use our own
user we create with sysusers.d/. That should yield same behaviour
everywhere (and also test sysusers a bit as side effect).
let's make sure we always invoke our commands through /bin/sh, since
on some distros su will use /bin/nologin (or whatever is listed in
/etc/passwd) as shell otherwise and we don#t want that.
To support ProtectHome=y in a user namespace (which mounts the inaccessible
nodes), the nodes need to be accessible by the user. Create these paths and
devices in the user runtime directory so they can be used later if needed.
The test exercises that PrivateTmp=yes and ProtectHome={read-only,tmpfs}
directives work as expected when PrivateUsers=yes in a user manager.
Some code is also added to test-functions to help set up test cases that
exercise the user manager.
PrefixRoute= was added by e63be0847c,
but unfortunately, the meaning of PrefixRoute= is inverted; when true
IFA_F_NOPREFIXROUTE flag is added. This introduces AddPrefixRoute=
setting.
Don't try to show top level drop-in for non-existent units or when trying to
instantiate non-instantiated units:
$ systemctl cat nonexistent@.service
Assertion 'name' failed at src/shared/dropin.c:143, function unit_file_find_dirs(). Aborting.
$ systemctl cat systemd-journald@.service
Assertion 'name' failed at src/shared/dropin.c:143, function unit_file_find_dirs(). Aborting.
The code existed in machinectl to use stdin/stdout if the path for
import/export tar/raw was empty or dash (-) but a check to
`fd_verify_regular` in importd prevented it from working.
Update the check instead to explicitly check for regular file or
pipe/fifo.
