In single-user mode I just `fsck /dev/da0s1a` and reboot. That fixes
the problem. However, I would like this to be automatic on boot. It
would be annoying if I'm out-of-town and the server cannot recover
without my help. Any tips?
fsck does run automatically when a filesystem does not get shut down
cleanly. However, fsck cannot fix all of the problems a filesystem can
experience without risk of loss of data. In those cases, there is no
option but to stop and ask the operator to intervene.
Won't soft updates solve this problem?

The handbook says. "We recommend to use Soft Updates on all of your file
systems." but doesn't mention booting specifically. This isn't something I
have tried (we boot over the network).
Your best bet is to avoid an unclean shutdown entirely. Buy a UPS.
We have lots of UPS systems. They constitute a "single point of failure",
a prodigous amount of hazardous waste every couple of years. I'd sure like
to drop them - and not on my foot.
I should say that we stopped using soft updates because the background
fsck was very slow, but that was on very large partitions. On a boot
drive with no user data, the timing would be fine.
