But after one proceeds with the default, how does one install more 
packages off the DVD? Mairin Duffy says in the bug report 
(https://bugzilla.redhat.com/show_bug.cgi?id=865922) that Fedora 
packagekit supported automatically recognizing of install DVD since 
2009! I've never found this feature and after this,
I installed F18 in a virtual machine and there is no such feature.

As KDE SIG, shouldn't we be concerned about how an ordinary user who 
selected the *default* DE during install can get KDE from the DVD?
