I have a fairly large stash of older install discs for *nix distros like Red Hat 9, Fedora Core 1, Mandrake 9.1, FreeBSD 4.8, Gentoo 2004, Knoppix 3.2/3.3/3.5/3.7. 1, and one of the Debian versions earlier than Sarge. All of these distros are up to much newer versions by now.
I can't imagine any reason to keep them around, but it seems like a shame to just throw them away. Any ideas on what to do with perfectly good old distros since which are unlikely to ever be installed?
