Well, you could make the device nodes available using --bind=, but
it's really ugly.

Generally, ext4/xfs quota require device access, and that's really not
such a good idea when mixed with containers.

btrfs quota makes a lot more sense there as they provide proper kernel
APIs, and in fact we already cover that nicely with "machinectl
set-limit".
