The interfaces should be in the order they are probed/created.

There isn't a feature to add dependencies, but there probably should be. I'm not sure that's really what the problem is there though. > At present, my rc.conf entries are: > # Need to do this manually to prevent alphabetical sorting. > network_interfaces=3D"wpi0 lo0 em0" > cloned_interfaces=3D"lagg0" > wlans_wpi0=3D"wlan0" > ifconfig_wpi0=3D"ether 00:16:36:f2:3b:84" > ifconfig_wlan0=3D"WPA" > ifconfig_em0=3D"up" > ifconfig_lagg0=3D"laggproto failover laggport em0" > ifconfig_lagg0_alias0=3D"laggport wlan0" > ifconfig_lagg0_alias1=3D"inet 192.168.2.50 netmask 255.255.255.0" >=20 > And this gives me a lagg0 at boottime without wlan0, since the interface = don't=20 > exist.

I know other people are using lagg this way so I'm a bit confused as to what's wrong. Enabling verbose start up and examining the output might be telling. -- Brooks > --=20 > Mel > _______________________________________________ > freebsd-current@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-current > To unsubscribe, send any mail to "freebsd-current-unsubscribe@freebsd.org" >=20 --qDbXVdCdHGoSgWSk Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (FreeBSD) iD8DBQFKSNK8XY6L6fI4GtQRAmLcAJ0QTa0uli7dmGqQsrnflpB/HlrezgCeMpz4 smSks3Ht3g8L+Rz8K8lOxF4= =f9tQ -----END PGP SIGNATURE----- --qDbXVdCdHGoSgWSk--
