+1 for this. Until recently I had an OpenBSD machine which had an initial install date some time in 1997. I rarely had to change any configs when upgrading. Virtually painless. It was my home mail and db server and was running on an ancient Compaq Pentium Pro 200 with 128Mb of RAM. It got replaced with Debian due to a complete hardware failure and I already had a Debian CD lying around and couldn't be bothered to download an OpenBSD ISO.
