Thanks Joorin, that might be an option. I'd still have to keep track of all files that "make install" installs in the ARMEL target filesystem, though, wouldn't I? I haven't read the pages related to packaging and deployment that carefully, yet...

The other option that came to my mind was to use something like unison to keep the ARMEL target and the device synchronised. That would require a unison server on the device, I believe. Once set up, this seems to be a fast way to update the device if I happen to need more stuff that's not in the repos.

Thanks for your replies Joorin and Daniel!
