i forgot that i have one machine where i can use aggr(4) because i
only have one switch upstream of it until i recently updated to 7.8;

: Checking root filesystem (fsck -fp /dev/sd0a)... OK.
: Mounting root filesystem (mount -o ro /dev/sd0a /mnt)... OK.
: ifconfig: vlan160: aggr0: SIOCSIFPARENT: Invalid argument
: ifconfig: SIOCAIFADDR: Device not configured
: ifconfig: vlan162: aggr0: SIOCSIFPARENT: Invalid argument
: ifconfig: SIOCAIFADDR: Device not configured
[...]
: Multiprocessor machine; using bsd.mp instead of bsd.
: fw_update: failed.
: Cannot fetch http://firmware.openbsd.org/firmware/7.8/SHA256.sig
: error: firmware.openbsd.org: no address associated with name
: Relinking to create unique kernel... done.

ok to add aggr(4) to these large ramdisks which I've build tested?
(ifconfig parts are the same for aggr as trunk)
