Re: re OpenBSD on booting from CDROM

[chuck <chuck@Yerkes.com>]

Sure, it'll stop being as slow as the hard drive and be as slow
as the CDROM drive.  Put it on a disk, pin the disk read only.
Use another disk for / swap and parts of var you need rw.
(it would be interesting to split up the parts of / that need to be
written to and those that didn't (/bin /sbin), wish union mounts were
more stable).
