I tend to disagree here. I have several racked servers running Debian
bo/hamm/slink (and other OSes too) that have no cdrom drive available.

probably but last time it occured (a libc problem), I was happy to be able
to find a static shell.

I often have to write shell scripts that must work on several Unixes.
I can't use bashisms because bash is not available everywhere. I just
need compatibility that is not provided by our /bin/sh :((
Unfortunatly, there's no way to get rid of bash in all Debian dists
because of all the packages that depend on it without any other reason
that no stand alone sh are available. This brings us to the inital subject...
we can't switch from bash to ash/ksh/zsh/etc without breaking everyting :(
