To even consider it requires ISO/IEC 10995 discs, a dedicated archival recorder, periodic testing strategy to know when to migrate data to new discs, and proper storage conditions (low temperature and humidity).
Sure, but I am not talking about "archiving for eternity".

I am talking about archiving for a couple of years (Typically 
life-time+ of a Linux-distro) to have a last-resort fallback at hand in 
situations, when no free usb-stick, no network or functional machine is 
at hand. These situations are rare, nevertheless they occasionally  happen.

In short, I adopted the habit to carry a Fedora-DVD in my 
Fedora-notebooks' case, because this had saved me from more serious 
troubles several times. I certainly could carry a USB-stick, instead ;)
