Question related to Fedora upgradation
I have been using fedora since a long. Lastly I upgraded it to 8 from 7 and now from 8 to 9. Now the question is y does it keep older rpms and noarchs. I mean still there have been .fc7.i386 and .fc8.i386 packages. Are they necesary to keep ? If i remove them then wud they arise any problem ?
Thanks in advance.
