[lxc-users] Allow quotas settings in container.

[Devon B.]

I couldn't figure out how to allow user/group quotas inside the 
container and I couldn't find many resources other than failed attempts 
or unresolved reports.

I received the same error as you and tried making a fake device using 
mknod to no avail.   The problem is that the rootfs (/) is always only 
mounted as (rw).  So then it tries to fall back to the other / in 
/proc/mounts which is the block device which isn't available in the 
container (for good reason probably).

I think the only possible way I had seen that quotas had worked was 
using a bind mount from the container to a host mount with usrquota 
enabled.  However, in my case, this did not seem appealing because I 
would have to maintain two filesystems for each container (rootfs and 
the usrquota) and from what I remember, the users/groups had to coexist 
on the host and the container so it would only be viable on one container.
