Code: Select all
cgroup on /dev/cgroup/cpu type cgroup (rw,cpu)
The address listed is populated with folders and files which, although I can open them easily enough and they are written in plain English, they don't contain anything that I can understand.
It doesn't come from fstab, and as far as I can tell it wasn't there yesterday.
So what is this and why has it suddenly appeared?
This is the definition of a cgroup from the Arch wiki:
cgroups (aka control groups) is a Linux kernel feature to limit, police and account the resource usage of certain processes (actually process groups). Compared to other approaches like the 'nice' command or /etc/security/limits.conf, cgroups are infinitely more flexible.
But I haven't created anything like that and probably wouldn't know what to do with it if I had.
I did update to gnome3 yesterday - has it got something to do with that? Or I guess it is possible, since I don't check the 'mount' command every day that it could have been there for some time and I just haven't noticed it.
I think I might be a bit happier if I knew that other people have this mount created as well.
All information gratefully received.
PS. This is on LMDE 64bit tracking testing. I haven't looked at anything else yet, I will do so immediately after posting this topic.
