After a couple of months I have my N900 with packages from extra testing/devel, installed manually with dpkg -i, and some stuff copied manually to the rootfs.

I'd like to remove them to stabilize my device and to use some chroot environment on the additional sd card to make experiment.

Any hints to find packages out of stable maemo feeds and files not owned by the package management system?

Thanks

Niko

Hmm--the only thing I can think of is backing up your list of installed programs, flashing, and then reinstalling. You could probably clean out manually copied files by doing a search against dpkg for each one, but that would probably take a long time, wouldn't do anything about the dpkg -i installs, and might delete some config files. I think the only way to know if a dpkg install came from the repos is to check it against the repos--it doesn't seem to be included in the dpkg status info.
