This should send a list of the floppy's contents to the list under this
subject:
find / -xdev | xargs ls -ldh | mail -s 'RE: [SLUG] Changing media' slug@nks.net
I thought about putting a '| gzip | uuecode' or '| gzip | mpack' in there,
but I didn't think I could get it right without seeing the errors..
I'm not sure how to put / on a RAMdisk. I've never done it, but I think
it has something to do with an initrd, See
http://www.linuxfaq.de/f/Files/initrd-boot.txt for clues.
You can skip dealing with that if you just mount a rw RAMdisk on /var/log,
and have / ro. That is, if Linux will deal with a read-only root. This
transition is much easier if it will. Or, if you get a HD instead of a
CF, nothing has to be ro. OTOH, a HD is noisier.
