I've read the man pages, configured fstab correctly, but when I do a
foot# swapon -a
swapon: /dev/wd1b: device not configured

The disklabel is:

footwd850|NetBSD installation generated:\

/etc/fstab:

/dev/wd0a / ufs rw 1 1
/dev/wd0e /var ufs rw 1 2
/dev/wd0f /usr ufs rw 1 3
/dev/wd1b none swap sw
/dev/wd1e /tmp ufs rw 1 4
/dev/wd1f /home ufs rw 1 5
/dev/wd1g /usr2 ufs rw 1 6
/dev/wd1h /usr3 ufs rw 1 7

Any ideas ?  Or do I have to have this device in my kernel config file ?

Cheers
Tim.
