Back in the days of NonStop Clusters for UnixWare, /usr had to be part
of the root file system. I can't remember the precise reason why, but I
doubt we need to have the same restriction on Linux.

To solve the chroot problem, we could just copy it into /bin of the
initrd and run it out of there.

SSI-specific commands that might be run before /usr is mounted, such as
cmount, should not be installed under /usr. They should be installed in
/bin or /sbin. In the case of cmount, it should be installed in /bin,
just like the mount command.

It's not a problem as long as the PATH variable is guaranteed to contain
the command's path. Just to be safe, the PATH variable should be set at
the top of a script if any commands outside of /bin are being called.

BTW, does your new Cluster Tools build system support installing into a
UML root image? I remember there were a few special things that needed
to be done, like installing a pre-written /etc/clustertab.
