That's why I always put a statically linked copy of my
favourite shell (zsh) in /bin, so I can even use it in
single-user mode.

Under some circumstances it can also be useful to have
an "emergency user" which is not dependant on anything
outside the base system (i.e. doesn't use anything from
/usr/local, doesn't have its home on an NFS volume,
doesn't has its account information on NIS etc.).  It
should be a member of the wheel group so it can do "su".

Best regards
