I built and installed a new version of -CURRENT which has this patch,
using the instructions at the bottom of UPDATING. To be certain - btx
doesn't need loading into the boot blocks, does it? bsdlabel -wB from my
7.0-RELEASE install and then using make installworld etc with DESTDIR
should ensure that the new boot binaries are installed?
If so, then unfortunately the patch does not help - btx still crashes with
a similar traceback to the one I originally posted.
I would be more than happy to test further patches.
