But why not put them in /bin? Just a guess, but a lot of the commands in /sbin require root privileges. If you put them in a separate place you can exclude them from a user's path. The same goes for /usr/sbin I suppose. It's not perfect though: /sbin/ifconfig is very useful to non-root users, but it's not in the path. Another example would be /sbin/lsmod (which a non-root user would need to get help on the mailing lists ;-) -- George Borisov DXSolutions Ltd
