This is probably your hard disk so you shouldn't need this.  You can
check by running 'camcontrol devlist'.

These are probably fine, but you may want to use a different group than
operator.  When you add users to group operator you make them rather
powerful.  They have full read access to every disk (via /dev/ada*) for
instance.  It is better to create a separate group.

This one is probably not needed either.

To burn a cd you may need write access to /dev/cd0:

own     /dev/cd0       root:operator
perm    /dev/cd0       0660
