Hi Guido,

I would be highly interested in your script.


Thanx in advance

I'm still using the old (legacy?) setup with one cgroup directory per container with all controllers attached to it (/cgroup/lxc/<container>/foo), therefore I just have to reach-in one directory via a calculated bind mount.

But this is just because I don't use swap space at all and you may easily add it  -- it's a diskless bladecenter and all filesystems are NFS. And to my knowledge, the only technical way to get swap on NFS is to loop-mount an image file - but this is an abstruse one.
