No, I had not done that, in fact, I didn't even know I needed those

I added options KDTRACE_HOOKS to my kernel config, built a new kernel,
and rebooted. I decided to try your script before things went sideways
so I'd have an idea of what to expect, and it didn't work:
dtrace: failed to initialize dtrace: DTrace device not available on

how about adding a periodic script to /etc/periodic/daily to backup the
information?
the idea was raised a long time ago already, but was abandoned [1].

Hi AK,
I've committed your patches to USB P4. I've made some additional patches.
Can you check and verify everything?
http://p4web.freebsd.org/@@181189?ac=10
Also please compile a kernel with WITNESS enabled to catch any LOR's, hence we
introduced another mutex.

I have been working on some devfs improvements and I am now posting the

multiple devfs mounts and/or symbolic links would be useful.
