init can just fall back to asking for a shell path or just start /bin/sh
instead if the real root shell fails.

[I forgot to suggest a little heresy in my previous mail, BTW. 
Why not just put tcsh and bash in /bin and be done with it? Sure,
they fit in well as packages, but they are so commonly used and shells
are nice to have static and available. It would add about ~10% to the
size of a distrib root filesystem.]
