Yes, but if you change to root permanently (su) - be shure to change back with
if you don't need it, because if you keep working as root, every file you edit will not be writable by you as a user + there are hundreds of ways to do irreversible damage just with typos like
# rm -r / usr/share/crap/
- as user you would just get 'permission denied'.
Thats why I almost never actually change to root.
