Matt, This patch fixes 2.8-RELEASE, but it no longer applies cleanly
to master; just resolving the conflict resulted in broken kernel.
The system stops booting in the middle of rc script because of
syntax errors in /etc/rc.subr (actually there isn't, and if I cp this
file to a non-HAMMER filesystem, no syntax error is detected).
Can you rework this patch for master (and if possible commit it too)?
