[packman] Re: [PM] pulseaudio 0.9.7 (openSUSE 10.3/x86_64)

[Wade Berrier]

Hi Toni,

Thanks for getting back to me on this.  Sorry it's taken so long to
respond.  I'm CC'ing Takashi for his input as well.

But yes, you are correct.  According to the policy, each of those
libraries should be in their own subpackages.

I still think it's overkill, and doesn't offer any benefit in this
particular situation.  Reasons:

     1. if a library, ie libpulse-simple, is updated, the rest of the
        libs built from the pulseaudio tarball will also be updated. 
     2. I can't imagine wanting 2 versions of libpulse or any related
        libs on my system.  I think this sort of change would be done
        when it's absolutely necessary, not in preparation for some
        future event that possibly may never happen.

The main rationale of the policy is to avoid #2.

Additional notes below...

Thanks for your effort on this.  I'm really looking forward to having
native pulseaudio support in suse 11.

Takashi, thoughts?

Wade

Well, the upgrade path has obviously been complicated :)  I had to
remove all the pulse rpms and then install fresh, just as you mentioned.
This isn't something that couldn't be fixed by some simple
provides/obsoletes.

Thanks again for your great packaging work in packman.  If it wasn't for
packman, it's possible I'd still be using Ubuntu :)
