Fedora user? Full root directory? Blame PackageKit
Looking at a system which I have been upgrading by a variety of mechanisms from F14 to F27 I noticed that its root directory (which I had on a separate partition for convenience) had started to become rather full. Muddling about with
du -sh -d 1 $name-of-directory
it became obvious that the prime bloat was all in /var/cache/PackageKit. Within it were directories for each of F23 to F27 taking up roughly 23GB in total. Some frenzied Googling turned up this bugzilla https://bugzilla.redhat.com/show_bug.cgi?id=1306992 Although the consenus seems to be that the problem manifests when using both dnf and PackageKit I am pretty sure that I only used dnf on this system. As hughsie notes PackageKit is only going to be in maintenance mode and everyone is scrambling to get Atomic and ostree in to shape. Meanwhile the solution seems to be to edit the PackageKit.conf to stop it cacheing downloads of RPMs. Then the older directories F23 updwards need to be nuked with good old rm -rf.
