First I define two machines in the same user namespace as two machines
with synchronized password files.

As today connecting two machines without synchronizing the password
entries is a problem, won't work, and is punted to the sysadmin to make
keep from doing something silly.

At the same time I don't want to make it easy to get confused, or cause

With these patches ocfs2 only still only works in the initial user
namespace. I don't set .fs_flags = FS_USERNS_MOUNT in struct
filesystem. Which means that while users in other user namespaces can
store files on ocfs2, they can't mount ocfs2.
