F9 whatis updates-new

[Gerry Reno <greno verizon net>]

I just upgraded this F7 machine to F9 as discussed in my previous post 
and now when I run the first 'yum update' it brings in PackageLibs plus 
'fedora-release' and a few others.  So when it installs this 
'transition' fedora-release it puts new repo files in /etc/yum.repos.d/ 
as .rpmnew so I check and move them into place.  The next 'yum update' 
now lists a whole bunch of files coming from repo 'updates-new'.  Is 
this normal?  Will the system still be usable if I install all these 
updates from 'updates-new' repo?

Regards,
Gerry
