Servers rebooted this aft ...

["Marc G. Fournier" <scrappy(at)hub(dot)org>]

Found out the hard way yesterday that daemontools and FreeBSD's unionfs
don't mix ... crashes the server hard ...

So, went through all the VMs that were using it today and did a manual
reboot to make sure that that doesn't happen again (the problem was if you
tried to kill a VM that had daemontools running, the server crashed with a
panic in fifo_close) ...

All is back up and running now ...
