tl;dr I was (originally) aiming to get backtraces for panics, intended 
panics.

The surprises with UFS were (originally) having no crash dumps after 
editing /etc/rc.conf to enable crash dumps; /usr/local/etc/sudoers empty 
after use of visudo; gdb not found after installing gdb; and so on. 
Eventually I discovered that all such losses were expected.
