su works because you end up with root's environment variables (and

No you don't:
[whooper@kenny whooper]$ su -c printenv | grep PATH
Password:
JAVA_PATH=/usr/java/j2re1.4.2_02
PATH=/usr/local/bin:/bin:/usr/bin:/usr/X11R6/bin:/usr/java/j2re1.4.2_02/bin:/home/whooper/bin

[whooper@kenny whooper]$ su -c "which up2date"
Password:
/usr/bin/up2date
[whooper@kenny whooper]$ sudo which up2date
/usr/bin/up2date
[whooper@kenny whooper]$
I assume they use xauth differently and that is why one works and the

"su" simply changes your UID and GID to root's. "su -" gives you root's
environment as well.
