I had to do a fresh installation of Fedora, the old one wasn't overwritten and I can mount the old filesystem in /media/something.
I want to query the old package database, but I can't find an option with yum to change the root (there is an option to change package installation root, but I guess it's not the case).
In other words, something that allow me to do:
# yum --changeroot=/media/something info old_package
Can yum do this? Shall another tool be used (e.g. rpm)? Or have I to read directly the database files that yum uses to keep track of packages (and which files)?
