I have mirror volumes which have survived almost 8 years with 2nd and third generation drives, motherboard, and architecture (32->64 bit). in those years, the newer revs which don't jump up and bite me in the ass probably go unnoticed.. abstractly speaking, the clearest working example of what breaks is oft-times a recent kernel on a recent install disk. slopping an install disk on a modern hard-drive consumes but a gnat's real-estate. using a symlink foundation does a pretty good job of allowing emerge to over-write the static known-good binaries with dynamics, but occasionally the gcc and/or libc is a repeatable failure and having the ro overlay handy allows wholesale excision of the broken installs, esp on young architectures. for whatever reasons, I pack my cd-rom drive bays with hard drives, and install with a cd-rom hanging off the side of the case tethered by its cables... right about the time its a bootable system the cd- rom comes off and the box is tucked into some crawl-space or other behind desks, shelves, etc. and hopefully forgotten.
