I proposed using symlinks for programs in */sbin to enable normal users to see them in their default path, but now I think this is a bit messy. (For instance, /sbin/ifconfig -> /bin/ifconfig, lots of these would be ad hoc)
For simplicity's sake, I think it's just good enough to include /sbin, /usr/sbin and /usr/local/sbin in user's default path. That way, filesystem standard compliance is not disturbed, and the users have those programs in their path by default. Thanks, __ Eray Ozkural
