Where the upgrade to the new format is done by dpkg, we could add downgrade scripts as well as upgrade scripts. As for new files, users already have to deal with different file formats (I.e. what if someone emails them a file from a newer/older version of Ubuntu), it may be wise to manually save the new files back in the old format before doing the downgrade. If gumptacular automatically upgrades ~/.gumptacular to a new incompatible format then gumptacular is broken and needs to be fixed (consider, for example, if you login to you account from both the SunOS lab and a Linux lab each with their own incompatible versions of gumptacular - you will have much worse problems with gumptacular than an occasional downgrade would cause). In general though I think it would be better to allow the user to install both the experimental and the stable version side by side, though this may make the packaging more complicated again. -- John C.
