From: Wolfgang Bumiller <w.bumil...@proxmox.com>
This is a larger patch set with the following goals:
* initial work for cgroupv2 support
* fewer hardcoded cgroup paths (required for cgroupv2 support)
* fewer patches on top of lxc
- This includes dropping the 'lxcnetaddbr' configuration patch and
adding that as a config variable explicitly.
The apparmor profile patch on the lxc side is still included, but we don't
use that profile anymore, that's for people explicitly overriding it.
(same for getent)
- The namespace separation has another chance of moving upstream, in a
slightly different way this time. For now I don't expect it to
impact the cgroup layout for us (much).
This also includes an lxc command socket client to more easily fetch
cgroup paths (and in the future this might replace a few lxc utility
run_command()s as well).
Note that the lxc-4 related configuration keys in the 2nd-to-last patch
are still subject to change, but the code should not affect
installations running lxc3 anyway.
