Hello out there
I'm on Manjaro (Arch) Linux.
Here, for newer kernels, cgroup has changed from V1 to V2.
This ends with "\"mountpoint for cgroup not found\" for Theory native
while Atlas native runs o.k.

So I have to set kernel parameter
"systemd.unified_cgroup_hierarchy=0"
to enable cgroup V1.

Is it impossible to update Theory native for running on both (cgroup V1 and V2)?
I'm not a programmer so kindly excuse this (maybe silly) question.

This affects all Linux systems using cgroups v2.
Theory's suspend/resume does only support cgroups v1 (freezer).
ATM there's no solution available as it would mean "somebody" would have to write the code to support cgroups v2.


... while Atlas native runs o.k.

Unlike Theory ATLAS (native)
- uses Singularity instead of Runc
- does not support suspend/resume.
