Right, and we're only interested in the new (userspace only) CMan, so no
need to consider the kernel code.

Do you mean that the user would have to add a configuration entry for every
single OCFS2 mount on their machine? Unless that's done automatically and
transparently (perhaps from mount.ocfs2), it's pretty much a non starter.
We've always wanted the users path (once the cluster stack is installed and
configured) to be as easy as a local filesystem: mkfs.ocfs2 /dev/foo; mount
/dev/foo /ocfs2.
