The issue seems more complicated:

root at mykerinos:/etc/pam.d# grep ENV_PATH /etc/login.defs
ENV_PATH        PATH=/foo:/usr/local/bin:/usr/bin:/bin:/usr/bin/X11:/usr/games
root at mykerinos:/etc/pam.d# su - spongebob
spongebob at mykerinos:~$ echo $PATH
/foo:/usr/local/bin:/usr/bin:/bin:/usr/bin/X11:/usr/games

spongebob at mykerinos:~$ grep SUPATH /etc/login.defs
ENV_SUPATH      PATH=/bar:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/bin/X11
spongebob at mykerinos:~$ su -
Password:
mykerinos:~# echo $PATH
/bar:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/bin/X11

Only "su" seems using ENV_SUPATH and ENV_PATH, not login. Doing the
same with login just gives me "sane" defaults for PATH both for
spongebob and root.
