Generally, you can do this if you allow yourself to have a swap
partition and a root partition on your hard drive. You link things like
the /usr partition to a directory on the cdrom drive you have mounted
under another directory. The root partition is required for writeable
things like /tmp. You might be able to get away with a ram drive for some
of this.
Note that a certain minimum number of files must be present on your hard
drive to boot to the point to mount the cdrom drive and link to its
directories. Slackware cd has done this in the past. It took less than
10 megs to have a 600meg cd loaded with apps.
There is no reason a zip disk should not work, if you repartition it and
reformat it.
