So there are two different points, /mem and /cpu. /mem has A and C and

/cpu, it should also move to A in /mem?


Maybe clearer to say that /mem has two cgroups, AB and C. The
abstraction provided by libcg would be of three groups, A, B and C.
Asking libcg to move a process to abstract group B would result it
moving to /mem/AB and /cpu/B


OK. Hmm, I've not really thought about it. At first thought, it should
not be very difficult. Only thing I am not sure is the arbitrary
grouping of the groups (ok, a bit confusing). If that information is
maintained somewhere, it should be pretty straightforward. (Only thing
is that I am not sure how it will be done, and where the grouping
information should be stored. configuration looks like the logical
place, but I am not sure)

Thanks,
