We shouldn't have any mirrors pulling from crater.  Does crater/pkgbox64
pull from git.dragonflybsd.org?  This would just be the git target.  I may
be oversimplifying this in my mind

I worry that if something bad happens to mirror-master/avalon right at a
release, it would cause a headache.  To eliminate that future headache,
we'd need either a bunch more hosts or more DNS flexibility.
