Are you advocating the use of the "rm -rf foo *" command, in addition to
editing the passwd files directly?

Likewise, if you edit the passwd files directly, unix won't stop you.
It will assume you know that normally the passwd files are locked before
being modified to avoid concurrent access problems, that for some reason
you don't care, and that you want to risk corruption of your passwd
files anyway.

Is there a good reason you want to risk corruption of your passwd files?
