It seems like you really would be better off using `envsubst`
(available on all my linux & BSD boxes with anything that installed
the GNU gettext package):

  $ path='/mnt/stick'
  $ echo "Path $path is it!" | envsubst
  Path /mnt/stick is it!

It's a lot cleaner and won't get hung up on things like paths that
contain pipes or other odd characters.

I'm not positive it's available in a busybox environment as I don't
have one readily at hand.
