If you think there's a problem with root's path in beowulf, I would say you are correct, but you mis-identified the cause of the problem.

In Beowulf:
- If you use su to become root, you keep the user's PATH, and need to use the full path to commands in *sbin, like this: /sbin/reboot
- If you use su - to become root, you get root's PATH and can run commands in *sbin directly, like this: reboot

To keep the old behavior, see https://dev1galaxy.org/viewtopic.php?pid=16456#p16456

It's like this:

if [ "`id -u`" -eq 0 ]; then
  PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"
else
  PATH="/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games"
fi
export PATH

It should be like this:

if [ `id -u`" -eq 0 ]; then
   PATH="/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games"
else
  PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"
fi
export PATH

you can check it simply by trying a user@machine# reboot
