Ok, so, as I said before...
1. User has nothing installed.
2. User follows some documentation and runs "yum install pkgA-blah" to
3. Package "pkgA" is not installed.
...the split makes no difference, either pkgA-blah implies pkgA or it
does not. If it does not and the user asks for just pkgA-blah, then we
don't give them pkgA.
Now you might argue that there are packages, for _both_ our examples,
where the user really does want pkgA as well (and it's not a strict

This example is a little more convoluted, esp. as F-12 doesn't have
-common before and -common always had it (and should thus. have used a
"Conflicts: nagios < 3.2.1-2" in nagios-common).
But here I think you have:
nagios-2 = Obsoletes: nagios < 2
nagios-common-2 = Obsoletes: nagios < 2
nagios-plugin-load = Requires: nagios-plugins = 1
nagios-plugins = Requires: nagios-common
...and then if the user does "yum install nagios-plugin-load" before
they've updated nagios-common then yum will install just nagios-common
But, again, you are _assuming_ that the user always installed nagios
for what became both nagios and nagios-common. This is not necessarily
