After testing dmraid-1.0.0rc15, I had downgraded a number of packages that were installed from testing back to there normal versions but had left dmraid-1.0.0rc15 and device mapper from testing.

Here is where I'm a little lost on the recovery procedure. I can manually assemble my raid array after booting to the install disk, but then what next?

My system is still broken and I can't figure out how to get around the readline error. I should have thought about this before going through the trouble of trying to set up the chroot to install bash, but the error I get when I try to execute chroot is thee *same* error I was getting when I tried to boot the system anyway. To try and recover, I booted from the install CD and then logged in as root.

I aleady had all of the current packages on my Arch system waiting to be installed, but I didn't know how to use the -r option to pacman. I do now ;-) From openSuSE, I had mounted the arch partitions and copied /var/cache/pacman/pkg over from my laptop after my latest update. So the '-r' option was the last missing piece of the puzzle.
