I have seen that there are differences in Menus and also in
installed
applications in KDE Desktop installed from the Netinst iso using the KDE
Desktop package selection in Anaconda, and in KDE Desktop installed from
Live CD. I filed a bug for one such discrepancy (
https://bugzilla.redhat.com/show_bug.cgi?id=1672312), but there are
definitely more.
We believe that both installation methods should result in the same
version of KDE desktop.
Can you please clarify?
