I've been using the following for some time:
keramida> su -
root# exec env SHELL=/usr/local/bin/bash bash -l
The same trick works with s/bash/mksh/ or s/bash/pdksh/, as far as I can
tell, and tcsh's history mechanism makes it easy to run the same command
later. All I have to type is "exec " and hit the arrow-up key :)
The env(1) trick makes sure that sub-shells use bash(1) too, and 'exec'
reduces the number of 'exit' commands I have to type.
Now, if there's a problem with bash(1), I will probably have to su
again, but that's less trouble than being locked out because gettext has
broken, the *default* root shell is bash and _that_ fails all the time.
