Public bug reported:
LXCFS 5.0 LTS was released last week.
The highlights of this is:
- Switch to meson build system
- Better detection and handling of CGroup2
- /proc/slabinfo support
- /sys/devices/system/cpu support
Of those, only the last two are user visible changes and just result in
more files becoming CGroup-aware in the container.
LXCFS 5.0 is an LTS release with 5 years support from upstream, that
along with future-proofing through the cgroup2 improvement is the main
reason why we'd like this to be in 22.04 LTS.
LXCFS is in universe as its main user (LXD) uses an upstream build in a
snap instead (already on 4.0). We nevertheless like to make sure that
Ubuntu LTS releases include the deb form of the LXC and LXCFS LTS
releases.
We already have this version of LXCFS deployed to all LXD snap users and other
than a few initial issues which are cherry-picked into the package, we've not
seen any major issue.
We are most likely to release a 5.0.1 bugfix release prior to final
freeze for Ubuntu so we can do the final 22.04 release without the
cherry-picks.
