I was explicitly asked to remove that hack, cc @CameronNemo
Btw, commit msg should be like incus: update service and it should also bump revision.

[dkwo]

Remove the cgroup changes. The user can fix the cgroups if necessary, but usually they should be using unified (i.e. cgroup2 only), and this would just be wrong in that case.

[sbromberger]

I think this breaks all systemd-based guests though.

[CameronNemo]

@sbromberger You can put it in your rc.local if it is necessary. It doesn't make much sense to have it in each individual container service. Alternatively I am pretty sure you don't need (and don't want!) this if you are using a pure cgroup2 setup. Just set CGROUP_MODE in rc.conf to unified instead of hybrid.

[sbromberger]

@CameronNemo - enabling unified worked (I had hybrid commented out but that apparently didn't do it). Thank you. I'll close this out.
