cgroup v2 is the next generation of the control groups API. This patch
replaces the cgroup v1 file systems with the unified cgroup v2 file
system.
cgroup v2 allows for things like containerd/podman to run rootless
containers and opens guix system up to running things like Kubernetes.
Thanks to Hilton Chain <hako@ultrarare.space> for suggesting the Docker
service change.
* gnu/system/file-systems.scm (%control-groups): Change to a single
"cgroup2" mount point.
* gnu/services/docker.scm (docker-shepherd-service): Trim 'requirement'
field accordingly.

Thanks to Guillem Jover <guillem@debian.org> on the OFTC's #debian-dpkg
channel for helping with troubleshooting.
Letting GNU Tar recursively walk the complete files hierarchy side-steps the
risks associated with providing a list of file names:
1. Duplicated files in the archive (recorded as hard links by GNU Tar)
2. Missing parent directories.
The above would cause dpkg to malfunction, for example by aborting early and
skipping triggers when there were missing parent directories.
* guix/scripts/pack.scm (self-contained-tarball/builder): Do not call
POPULATE-SINGLE-PROFILE-DIRECTORY, which creates extraneous files such as
/root. Instead, call POPULATE-STORE and INSTALL-DATABASE-AND-GC-ROOTS
individually to more precisely generate the file system. Replace the list of
files by the current directory, "." and streamline the way options are passed.
* gnu/system/file-systems.scm (reduce-directories): Remove procedure.
* tests/file-systems.scm ("reduce-directories"): Remove test.
|

* gnu/system/file-systems.scm (file-prefix?): Return #f unless both file names
are absolute or relative.

Tools such as efibootmgr rely on the deprecated /sys/firmware/efi/vars API as
well as on the new /sys/firmware/efi/efivars API. The latter needs to be

Conceptually a UUID is just a bytevector. However, there's software out
there such as GRUB that relies on the string representation of different
UUID types (e.g., the string representation of DCE UUIDs differs from
that of ISO-9660 UUIDs, even if they are actually bytevectors of the
same length). This new <uuid> record type allows us to preserve
information about the type of UUID so we can eventually convert it to a
string using the right representation.
