no but ... ... > (For storage devices there's the DUID-based mounting already though, so > I guess those are a non-issue.) right. so we'll ignore those...but that's a hint: there's more than one way to do things. > Some things in the OS are specified per interface/device name, e.g. PF > rules (e.g. "pass in proto tcp from any to cdce0 port 123 rdr-to cdce1 > ..", "match out on cdce0 from 192.168.0.0/16 to any nat-to cdce0"), so > having the interface numbers garbled on replug may be an unnecessary > reason to > reboot?http://www.providr.com/now/spartans-facts/26/?utm_source=fbkxd&utm_medium=spartan_d_f My thought would be to have an include file in your pf.conf that defines a macro to the desired interface to what it happens to be connected as this moment. So maybe a hotplugd(8) script that looks at the MAC address (or ... something else?) of whatever device was just plugged in and create an entry in /etc/pf/interfaces.inc something like ext=run0 or int=run1 as appropriate. Have an 'include "/etc/pf/interfaces.inc" ' in your pf.conf, and reload pf.conf when a hotplug event takes place. Nick.
