OpenBSD firewall on CD

["Raymond C. Rodgers" <rcrodgers_(_at_)_worldnet_(_dot_)_att_(_dot_)_net>]

Hi,
 I'm setting up a firewall for home use, and I was wondering if it might 
be possible to make a bootable CD with the firewall, and use a small hard 
drive for /tmp and /var directories. Does anyone have any ideas about how 
to do such a thing, and comments on it both positive and negative (from a 
security standpoint as well). I'd most likely burn the configuration to a 
CD-RW disc, and put a cheap 32-40x EIDE CD-ROM in the box to boot from.

Thanks,
Raymond
