Greetings all,
I deserve the "stupid moron of the decade" award....no question.
I'm embarassed to even post this to a mailing list.
In the excitement of adding software (in this case bash) while su'd to 
root, I went to chsh...and while changing the shell failed to complete 
the correct path to bash for root. Now I cannot su.

I did "chsh" while su'd
in the text file I amended the path to read /usr/pkg/bin/csh instead of 
/usr/pkg/bin/bash
of course an error was generated by the shell...and this was it:
pwd_mkdb: warning, unknown root shell

I have the horrible feeling I just locked myself out and a reinstall is 
the only option.
This is such a n00b thing to have done.
Does anyone have a suggestion as to a way of rectifying this??
as "me" I'm in the group wheel and also staff...but at this rather 
flustered moment cannot think of any use I could put that to.

Yours in complete mortification,
-Colin
