Quick question on newfs

[mal content]

I was setting up encrypted swap with GELI and accidentally
blew away my /tmp partition with:

# dd if=/dev/random of=/dev/ad0s1e bs=1m

Understandably, it will no longer allow me to mount /tmp,
so how do I use newfs to recreate the partition? I want to
be absolutely sure before entering any disk modifying
commands (just like I was absolutely sure last time...).

I'm guessing it's as simple as:

# newfs /dev/ad0s1e

cheers,
