well... I don't really know...
I expect it to be from the rc.d script which is run by /bin/sh (which is
/bin/bash on slackware).

yes I did.

looks like the 'cu' command runs bash (or sh, which is a symlink to
bash) and '-m' makes it believe the next args is a command rather than a
username.

I didn't succeed in compiling the "shadow" package with the "new" su
command, so I can't tell for sure that it is "su" related.
But, in ChangeLog, from "shadow-4.0.14", I read:

<...>
        * NEWS, src/su.c:
        added handle -s/--shell, -m/-p/preserve-environment options like
GNU su
        (based on patches from Debian submited by
        Nicolas Fran=C3=A7ois <nicolas.francois@centraliens.net>)
<...>
########################################################################

This date corresponds to the release of "shadow-4.0.14".
Debian (sarge I think) seems to have a lower version too, but Zafer said
"<...>the option exists in all Linux distributions, I know." ; so I'm
puzzled :-/
