[lxc-users] Attach a lxc container to an existing cgroup ?

Quoting Jäkel, Guido (G.Jaekel at dnb.de):

Of course, you just can archive similar settings for a group and can't directly control the sum of an aspect (e.g. memory), but I wonder if this real constructive.

But you may write a little script that will re-read the lxc configuration and update the definded cgroup entries. @Serge: Such an lxc-reconfigure command may be something to add to the lxc package.

What would the lxc-reconfigure command do exactly?
