As registering the container creates a scope which might not be cleaned
up completely before we run a next command in the same container,
causing intermittent test fails:

Since even systemd-nspawn's man page suggests not to register containers
with systemd-machined if they don't run a service manager, let's do just
that to mitigate the race.
Resolves: #39629
Regular generated paths make it hard to identify individual GPIO
devices. This is a challenge when using multiple USB-to-GPIO adapters
like Diolan DLN2.
The unique symlinks from this rule can be used, e.g., with gpiod tools.
The same service name was accidentally used for two invocations:

Closes#35788
This gives access to credentials within ExecCondition=. As described in
ticket #35788, I do have a use-case for this and as noted in the
commit that dropped this[1], this is OK to be revisited if there are
use-cases.

systemd-repart is incorrectly choosing the loop-mount
code path to copy files after formatting, instead of using the --rootdir
path, which is required by mkfs.btrfs to apply compression (since it's
on files, not the fs).
So two fixes (and an integ test):
1. If Btrfs compression is requested without a root directory (e.g.,
Compression= without CopyFiles=), we now log a warning and skip the
--compress flag. This prevents the mkfs.btrfs failure, and it's
meaningless anyway without any files.
2. The logic in repart now uses the --rootdir code path whenever the
partition is btrfs and compression is requested. Otherwise it still
won't work even in the legitimate case because use the loop mounting
code, which is too late to use --compress.
Fixes: https://github.com/systemd/systemd/issues/39584
Add testcase_btrfs_compression() to verify that btrfs partitions with
Compression= and CopyFiles= directives work correctly.
The test verifies the fix for issue #39584, where mkfs.btrfs would fail
with "ERROR: --compression must be used with --rootdir" when repart
tried to create compressed btrfs filesystems.
The test creates a partition definition with Format=btrfs,
Compression=zstd, and CopyFiles=, then validates:
1. systemd-repart output shows "Rootdir from:" and "Compress:",
confirming that the --rootdir code path is used
2. mkfs.btrfs is invoked with both --compress and --rootdir options
3. The file is successfully copied to the filesystem
4. Compression is actually applied (verified via compsize output
containing "zstd")
- use loop for checking existence of functions,
- rename HAVE_LIBARCHIVE_XYZ -> HAVE_ARCHIVE_XYZ to make them match with
the function name,
- do not conditionally include user-util.h in libarchive-util.h,
- sort library function symbols.
