This is currently not correct in some files (i.e.
/etc/defaults/rc.conf).  Can it be fixed so that everyone points to
/var/run/named/pid?  This is hosed for a non-chrooted system since bind
doesn't have permission to write in /var/run.

Also, the /etc/rc.d/named script will do an

ln -fs "${named_chrootdir}${pidfile}" ${pidfile}

if named_symlink_enable is set (which is by default).  Please protect
this with

if [ -n "$named_chrootdir" ]; then
...
fi

for those who do not have a chrootdir.  Otherwise we end up with a
recursive link.

This is broken too.  If named_chrootdir isn't set, then confgen_chroot
doesn't get set and it messes up the invokation of rndc-confgen.  I
think taking the "" off of the ${confgen_chroot} will solve this but I'm
not sure.

It would be nice to have it all working while you make these changes.
