Hi, a proof of $Subject: [nico@nico2 ~]$ rpm -qa | grep -i firefox firefox-2.0.0.9-1.fc8 firefox-2.0.0.9-1.fc8 [root@nico2 ~]# du -sh /usr/lib/firefox-2.0.0.* 6,8M /usr/lib/firefox-2.0.0.6 20K /usr/lib/firefox-2.0.0.8 43M /usr/lib/firefox-2.0.0.9 Obviously rpm -qif on /usr/lib/firefox-2.0.0.6 and on /usr/lib/firefox-2.0.0.8 reported that the directories weren't owned by any package. Same problem with kernel modules (that occupied a much larger amount of space). Why aren't these files removed? I run yum clean all regularly. Is there a way to purge entirely old packages? Thanks, Nico
