Ya pas deborphan pour Fedora, je vais essayer KleanSweep et RpmReaper.

KleanSweep :

Reclaim disk space by finding unneeded files
KleanSweep allows you to reclaim disk space by finding unneeded files. It
can search for files based on several criteria: you can seek for empty
files, backup files, broken symbolic links, dead menu entries, duplicated files, orphaned files (files not found in the RPM database), and more.

RpmReaper :

A tool for removing packages from system
rpmreaper is a simple ncurses application with a mutt-like interface that allows removing unnecessary packages and their dependencies from the system.

J'en ai profité pour installé le plug-in delta-rpm de yum, j'espère qu'il s'agit bien d'un truc qui peut accélérer les majs ?
