Does sysctl have a facility to do this?

I might actually suggest making that the only way and have if.1.name be available. -- Brooks [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (FreeBSD) iD8DBQFHvZeYXY6L6fI4GtQRAq+SAKDWoU2VUwWkotuw0L46r8MGqzarVQCeJb+6 eOUZsjvip/UzKDo0m+7EEQI= =T+v0 -----END PGP SIGNATURE-----
