check-update question

Hi,

We've got a custom repository that hosts all of our self packaged RPM's 
and have grouped all of the RPM's together in a group called ifp-base. 
We run a daily script that uses "yum check-update" to verify whether we 
need to run a full update.

check-update behaves as expected if we add an updated version of an 
existing RPM, the problem is that it doesn't seem to know that we've 
added a *new* package to the group, so as far as our script is concerned 
there is no updates to be run even though there is a new package in the 
repo.

We're running Scientific Linux 5, which includes yum 3.2.8.

Thanks,

Barry
