Achievement Unlocked. RPi image made, restored and tested on a separate Pi. I've got a working backup of The Sanitarium now.
Now to upgrade the production image to the latest version of Citadel and migrate it to the i5.
This ought to be interesting. I do not trust that the upgrade is going to work right on Raspbian - so many other things not working quite right on that platform. But at least if I F it Up, I can go back.
Subject: Citadel 930 released
For those of you who have been waiting for RSS feeds in international languages to work properly, now is your time to gobble down the latest Citadel server, now available through Easy Install or through source tarballs.
This is also the first version of Citadel to use the new inbox rules handler.
If you had inbox rules configured before, they will carry over to the new system. Basically we're no longer using Sieve or libSieve, so this removes the dependency on an apparently abandoned library that some people were beginning to have trouble compiling.
This message serves as the release notes.
