AFAICT, that does not solve the problem, that e.g. kubernetes gluster
(or ceph) plugin will call the host's mount(8), which will need to find
a mount.glusterfs helper script (on the host) that will call
mount.glusterfs in the container. The easiest way is to have a writeable
/sbin/fs.d that containers can install into.
