I've submitted two PRs to help others find this info in the future. augment if_tuntap man page on source of autogenerated MAC (/etc/hostid) https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=255294 man page for /etc/hostid and pointer in sethostid/gethostid(3) to /etc/hostid https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=255293 If I find the time, I'll try to submit the necessary patches. -- p...@freebsd.org +49 171 3101372 Now what ? _______________________________________________ freebsd-net@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
