I got stuck in /etc/rc.subr studying the devfs routines without thinking
to search for where they were called, /etc/rc.d/devfs.

Thats a leap I still haven't grasped from documentation and reading the
scripts. Exactly the sort of thing hoped for by asking here!

First couple of tries on variations of that didn't go. When is
devfs.rules read? This did work:
devfs add path 'bpf*' mode 0660 group tcpdump
But by that time I had "devfs -m /dev ruleset 5" in effect which may
have contributed to "devfs add path".
/dev/bpf2 didn't exist, as mere user I launched tcpdump on my vlan0
device and /dev/bpf2 was created correctly! Hurray! Will see if
'devfs_system_ruleset="devfsrules_bpf"' works on reboot sometime later.
