- confile: forbid absolute paths in config items that modify the cgroup layout · f63ef155
  Christian Brauner authored Feb 15, 2021
```
This is not a safety measure but merely is supposed to raise awareness that
these paths are always relative to the cgroup root as determined by
lxc.cgroup.relative.

cgroups: first batch of cgroup mounting fixes

- cgroupfs: rework cgroup2 mounting · a3e5ec26
  Christian Brauner authored Feb 15, 2021
```
We now explicitly refuse to mount cgroups on pure unified layouts when the
container is not running in a separate cgroup namespace. This is not a
regression since we simply always failed before anyway. I will likely fix this
very soon though. But there are bigger fish to fry currently.
