bash and su without - option do not work well together

[Siem Korteweg]

Hi,

Program su limits PATH before starting the new process (as it should do!). Without the - option, /etc/profile is not called and several programs from .bashrc cannot be found:

(***@milax)$ echo $0
-bash
(***@milax)$ echo $PATH
/usr/sbin:/usr/bin:/sbin:/usr/X11/bin:/usr/sfw/bin:/opt/sfw/bin:/opt/sfw/sbin:/usr/gnu/bin:/usr/dss/bin:/usr/dss/sbin:/opt/csw/bin:opt/DTT/Bin
(***@milax)$ su
