It's fine with me (we do that sort of thing in qemu), but when Stéphane
objected I thought it was about another problem he had with the synced
packaging.  Stéphane, do you have a problem with just dropping |
cgroup-lite from the dependencies for lxcfs?  I see we'd have to add
cgroupfs-mount to trusty-backports, but other than that it should be ok.
