Yeah, mount --bind is cool, I've been using it on one of my projects
today. But - maybe I'm just not thinking creatively enough - what are
the advantages of mount --bind versus just symlinking?

Also, I tried mount --bind fileone filetwo, and it fails if filetwo
doesn't exist. ('mount point filetwo doesn't exist'). Is that supposed
to work? (using mount from latest redhat beta)

BTW, pivot_root is nifty, too. ;-)

David
