I finally bricked my NetBSD system

[Bob Bernstein <poobah%ruptured-duck.com@localhost>]

There's a long back-story to this event, but it's not important.

Suffice to say that I removed all the packages from my system, 
including the shell I like at /usr/pkg/bin/tcsh, and now all my 
attempts to login are rejected because the shell cannot be 
found.

Is there a work-around?

Thank you

 think, of ascertaining what is right or wrong, and not a
 consequence of having already ascertained it.
