Thanks!

Looking on falla, I actually don't see any /dev/diskid/ entries
listed in /proc/partitions, so I guess this is not possible right
now; not sure why.

It's something we should implement in debian-installer for
sid/stretch. Similar to the UUID entries used on Linux for
many years now.

Odd error message. Was it unmounted? (not just mounted read-only)
I would also have tried to call fsck.ufs directly for good measure.
If you do have the chance to try it again, it may be useful to
install ktrace first and use that to get a system call trace
(ktrace.out) to analyse later, e.g.:
# ktrace -di -- tunefs.ufs -j enable /dev/vtbd1s1
I can meanwhile try to find a way to reproduce it myself.

For jessie, when /etc/default/grub has GRUB_TERMINAL="serial console",
I'd like those flags to be set automatically by /etc/grub.d/10_kfreebsd.
When I've finished that, we could replace falla's modified
/etc/grub.d/10_kfreebsd with a pristine copy.
Thanks again,
