Re: Question about a package conflict

Answering my own question: "Yes."

Let's say I have 2 packages 'a' and 'b' that want to register the same 
keys but in different schema files.

Install a, gconf registers the keys with a's settings.

Install b, and then the keys are registered with b's settings.  Remove 
b and the keys can disappear, even though a is still installed.

So to recap the options Steve mentioned:

Unfortunately it doesn't look like that will work, given what's above.

I agree.

I agree.

Unfortunately, they don't have the same contents: they have different 
default commands for handling the url.  Maybe the maintainer of 
last-exit and I could agree to make them the same, but then we'd have 
to do alternatives for the schema file *and* alternatives for 
'/usr/bin/lastfm-player' or some such thing.  Or am I missing 

I guess there is option 5: forget the schemas file entirely and just 
use gconf/defaults/10_lastfm, like before.  #369907 won't be happy, 
because of the "This key has no schema" message, but it's less hairy 
than the above.

Any thoughts?
