I've tested this again and it seems like if we use unprivileged
containers, set(x)attr calls fail, this is what I got for a volume
creation request on that container:

[root at 8f267d6c6146 glusterfs]# gluster v create test-vol
172.17.0.1:/tmp/b1 force
volume create: test-vol: failed: Glusterfs is not supported on brick:
172.17.0.1:/tmp/b1.
Setting extended attributes failed, reason: Operation not permitted.
