if fso-foo has

Conflicts: foo
Replaces: foo

but not

Provides: foo

opkg will always pick fso-foo when it's present in deploy, while you 
want an image with foo.

The whole problem is that for some images I do *not* want to drag in 
python, frameworkd and other things when I just want /usr/bin/apm or 
/usr/bin/gpsd. But for fso-*-image I *do* want fso-gpsd and fso-apm.

If the fso stuff was API+ABI compatible and about the same size I 
wouldn't care about this, but right now it's a ~5MiB difference, not to 
mention the runtime speed penalty of needing a python interpreter.
