I'm still impressed with the Mandrake 10 Linux distro (now known as Mandriva). Previously, an install of Mandrake 10 brought an ancient K6-233 back to life for me as a security camera capture system. Alas, the summer heat finally fried the CPU in the K6. I grabbed (yet another) old machine from the closet, pulled the drive from the K6, stuck it in the other machine… and it booted fine. Mandrake automatically recognized its new home and preserved all of my configurations, even though nearly every piece of hardware was different.
Pretty impressive, especially if, like me, you're used to recompiling the Linux kernel each time you make a minor hardware change.
