`MatchPattern` for regular-file and directory as target can now match
subdirectories This is useful to install files for examples in `.extra.d`
directories:
```
[Target]
Type=regular-file
Path=/EFI/Linux
PathRelativeTo=boot
MatchPattern=gnomeos_@v.efi.extra.d/apparmor.addon.efi
```
The if the directories in the path do not exist, they will be created. Whereas
the part in `Path` is not created.
The article "a" goes before consonant sounds and "an" goes before vowel
sounds. This commit changes an to a for UKI, UDP, UTF-8, URL, UUID, U-Label, UI
and USB, since they start with the sound /ˌjuː/.
While we are at it, replace the sloppy use of filename_is_valid() by the
less sloppy filename_part_is_valid() (as added by the preceeding
commit), since we don#t want to be too restrictive here. (After all,
version strings invalid as standalone filenames might be valid as part
of filenames, and hence we should allow them).
As described in the BLS, we should place binaries into the XBOOTLDR
directory if it is available, otherwise into the ESP. Thus, we might
need to put binaries into /boot or into /efi depending on the existence
of the XBOOTLDR partition.
With this change, we introduce a new PathRelativeTo= config option that
makes this functionality possible
Chasing symlinks is a core function that's used in a lot of places
so it deservers a less verbose names so let's rename it to chase()
and chaseat().
We also slightly change the pattern used for the chaseat() helpers
so we get chase_and_openat() and similar.
Instead of exposing just the partition type UUID, let's expose the
GptPartitionType struct, which has a lot more information available
in a much more accessible way.
Also, let's get rid of SECONDARY/OTHER in PartitionDesignator. These
were only there to support preferred architectures in dissect-image.c,
but we can easily handle that by comparing architectures when we decide
whether to override a partition. This is done in a new function
compare_arch().
This is a high-level function, and it belongs in libsystemd-shared. This way we
don't end up linking a separate copy into various binaries. It would even end
up in libsystemd, where it is not needed. (Maybe it'd be removed in some
optimization phase, but it's better to not rely on that.)
