/etc/defaults/rc.conf are the defaults. Not everyone makes a new
system with sysinstall(8), and having sysinstall(8) put new and
unexpected things in rc.conf is in itself a POLA vilolation.

I was talking more about running named(8) as bind:bind. Chrooting has
other issues, you need to actually build a chroot environment
somewhere and decide what to put in it, and you still need to run as
bind:bind for chrooting to be much of a security measure.

Running named(8) as bind:bind by default is easiest done by changing
the named_bind flags. As I said, changing the default would break
stuff, but if you look at /etc/defaults/rc.conf in -STABLE,

named_flags=""			# Flags for named
#named_flags="-u bind -g bind"	# Flags for named

So the hint is already there. And if you look at -CURRENT,

named_flags="-u bind -g bind"	# Flags for named

It already runs that way by default.

But if you really want to be clever, you should run named(8) in a
"It's always funny until someone gets hurt. Then it's hilarious."
