When I do a rebuild with -vv here, the last command shown is "D: removing directory /var/lib/rpmrebuilddb.9081" I did an experiment (actually quite a few but what they led to was): mkdir /tmp/foo rm /tmp/foo/* rpm --dbpath /tmp/foo --initdb cp -p /var/lib/rpm/__db* /tmp/foo rpm --dbpath /tmp/foo --rebuilddb # All the files in /var/lib/rpm/ are now in /tmp/foo/ but are smaller. # The __db* files now have current time, not time they had in /var/lib/rpm/. rpm --dbpath /tmp/foo --verify coreutils # <reports that coreutils is not installed> rm /tmp/foo/* rpm --dbpath /tmp/foo --initdb cp -p /var/lib/rpm/Packages /tmp/foo rpm --dbpath /tmp/foo --rebuilddb # Above comand takes long time. Sizes of files in /tmp/foo/ now same # or close to size of files in /var/lib/rpm/. Time of Packages file # unchanged from /var/lib/rpm/. rpm --dbpath /tmp/foo --verify coreutils # <reports coreutils is ok> >From this is seems like /var/lib/rpm/Packages is *the* database. But I would still appreciate confirmation from someone. -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
