I think is was an "inadequacy" of the bsdinstall system.  I booted a thumb
drive which, of course, was named /dev/da0. I plugged in a USB hard drive
which was /dev/da1. bsdinstall does not label any partitions and generates
/etc/fstab that assumes that the root is on the drive it was on during
install. This works reasonably well for non-removable drives, but that USB
drive is created as da1 when I boot. I simply managed not to see it was
trying to boot /dev/da1p2 when I booted the system.

I booted my 10.1-BETA1 system and edited /etc/fstab and it did fine... for
a while. I was doing a "portsnap extract" and, late in extracting devel,
the system panicked in vfs. I did not get a dump or any information from
the crash. Sorry.

After I booted my 10.1-BETA1 system, I had to do a full fsck and, after
that I had a totally empty usr, so I guess I need to try again from
scratch. :-(

If it happens again, I'll try hard to get more information. For tonight,
I'm calling it quits and I'll start over tomorrow.
