Yeah, but they will exit with an error. I think that's what Raphael
wanted to avoid. But you have a point, since:

        <param>-s /bin/bash</param>
        <param>|| true</param>

can be used for that.

Brendan Taylor suggested that "|| true", AFAICF (could find ;).

I don't think it would, because of that ^. But it would, if there is
a user "lfser". :) So I think:

    grep '^lfs:' /etc/passwd

would work (where lfs should be &lfs-user; in general).
