This is a problem, but it's not just with FreeBSD - obviously if you
follow these instructions then you're just giving root to members of
gdmaint, not wheel (which may in fact be worse, if you trust people to use
gdc who you don't trust with the wheel bit (i.e. those who can legally su
to root if they knew the password)).
