Also, I am running 9.2-Stable with fuse in the kernel (not a module) backported from the 10.0 code and the mount_fuse from 10.0, as well, so mine is a rather odd system. I should be able to capture dump, but I don't have one now. I should also mention that the FreeBSD kernel code was updated in July to 7.10, but was reverted five days later to 7.8 due to issues with fusefs_libs not getting along with it. At the time it was suggested that fusefs_libs would need to be updated to match. (I have no idea how tricky this might be, but it is way beyond my capability. Guess it's almost time to update to 10.0. I really should have moved to HEAD before 10-STABLE was branched. Then I'll be running fully supported code. -- R.
