This is a solved problem. Assuming we are running (from WORM media like
CD) Linux, we can mount the filesystem on the HDD "noexec" and use it
strictly for data; alternately, both "ro" AND "noexec" would enable us to
use it strictly as a data SOURCE by eliminating write capability as well.

As far as our choice of media, I would strongly recommend AGAINST using
flash/memory stick for boot media precisely because it admits subsequent
writes. Using CD-ROM, and strictly CD-ROM, guarantees a write-once
scenario. However, that doesn't preclude us from using inexpensive CF/IDE
flash media as an alternative to a real HDD for things like logging, swap,
etc. where we may wish to keep local state information on writeable media.
