It should, but I'll have to see if anything useful hit the disk before
it wedged.

top of tree was 0b0585c3e192967cb2ef0ac0816eb8a8c8d99840 I think.
(That's what it is on my local box that I pull all my test trees from,
and I don't think it changed after I started that run, but I'll
double check on Friday)
I don't use the auto config, because I end up filling up /boot
unless I go through and clean them out by hand every time I install
a new one (which I do probably a dozen or so times a day).
Is there some easy way to prune old builds I'm missing ?
