Hrm.  Shirley, there's some name in there it could use safely...?  Whatever
that name is, checkroot.sh could mount a tmpfs on /dev/shm/<thatname> and
create the root dev node under it.  BTW, checkroot.sh *does* remove the
'root' node, once the fsck is done, so what's the pollution issue?

What's the mtab.sh problem?
