Hi there,

I'm a bit puzzled about the problem as well, because according to

-l should work. Also, at least with GNU coreutils it doesn't make any
difference whether you use 'su -' or 'su -l'. su puts the basename of
the shell of the user that is su'd to into argv[0], prefixed with '-' to
indicate a login shell.

Bash's and ksh's manpages mention this, tcsh's manpage is imprecise in
saying argv[0] has to *be* "-" but its code only checks for the first
character being '-' (or the -l flag, as the manpage says).
