Maybe you where thinking of me.  For manufacturing purposes we made a
bootable CDROM.  It mounts the CD as the root file system.  I modified
/etc/rc to fdisk/disklabel/newfs the IDE disk drive and then copy
/var on to the IDE disk drive.  Then mount it as /var and boot to
multi-user.  We actually copy some more stuff to to IDE drive for
loading system since CD-ROM are not a good random access media.
Even the fast ones are slow as shown by doing a login until it gets
cached in ram.  The floppy is useful to configure the image (just set 
the BIOS to boot the CD).
