I've heard often that it is better to su to root rather than log in directly as the root user (and of course people also say that it's even better to use sudo). I've never really understood why one is better than the other(s), insight?

If I run a script from /home/<user>/<dir>/script.sh , as root, the cron works pretty well. But If I run the script from /root/<dir>/script.sh (as root, again), the cron does not seem to work.
