Oh, they install stuff on the device all the time?-)

I meant frequency of use by "rarely used".

Build environment as in the Maemo and packages as in the existing
dbus/ dir contents (bad wording, sorry). If you need to port all of
Maemo to a new pkg management just to use ipkg, well...

Granted, you need to recreate the packages for AI currently too so
perhaps it's not an issue.

Cool too, though nothing special really. There's scripts around for
generating the bulk of debian/ anyway.
