This is specific to Fedora's tag setup. Other folks know more about that 
than I, but I don't see a reply yet so...

dist-f15 is where the builds for the gold release of Fedora 15 live. Now 
that F15 is released, this tag should not change.

dist-f15-updates is where updates for F15 go. Builds are tagged here as 
part of the update process.

dist-f15-override is used to hold builds that need to be in the 
buildroot for dependency reasons, but are otherwise there. Normally this 
happens when you have two interdependent updates. These get built in 
dist-f15-updates-candidate which does /not/ feed into the buildroot. 
Such buildroot overrides are managed by Bodhi

When the build is part of an update that goes live

When the build is needed in the buildroot but is not yet released. 
Normally such a build would eventually get into the -update tag, but it 
is possible that the update will fail testing and not be released, in 
which case (I presume) Bodhi would eventually remove it from the 
-override tag.
