When I upgraded the hardware underlying the machine, I created separate logical volumes called root64, usr64, and var64. I installed the 64-bit system using those logical volumes, copied over /etc from the old root to root64, and rebooted. This isn't automatic, but it was a lot easier than it might otherwise have been. It is, however, trivially automatable. Multiarch might make it even easier, I don't know. -- brian m. carlson / brian with sandals: Houston, Texas, US +1 832 623 2791 | http://www.crustytoothpaste.net/~bmc | My opinion only OpenPGP: RSA v4 4096b: 88AC E9B2 9196 305B A994 7552 F1BA 225C 0223 B187
