This post shows how to bisect a Fedora kernel to find the source of a regression. I needed that recently and I found no good guide, so I’m at least capturing my notes here, perhaps you find it useful. This approach can be used to identify which exact commit caused a bad kernel behavior on … Continue reading Bisecting Fedora kernel
As previously announced, Taskotron (project page) will be shut down today. See the announcement and its discussion for more details and some background info. As a result, certain tests (beginning with “dist.“) will no longer appear for new updates in Bodhi (in Automated Tests tab). Some of those tests (and even new ones) will hopefully … Continue reading Taskotron is EOL (end of life) today
I’ve already written about this in 2017, but things got simpler since then. Time for an update! If you use virtual machines, your disk images just grow and grow, but never shrink – deleted files inside a VM never free up the space on the host.

If you click on it, you’ll get a full log with rpmlint output. If you wish to whitelist some errors which … Continue reading Whitelisting rpmlint errors in Taskotron/Bodhi
Update: This got significantly simpler with newer qemu and virt-manager, read an updated post. If you use VMs a lot, you know that with the most popular qcow2 disk format, the disk image starts small, but grows with every filesystem change happening inside the VM. Deleting files inside the VM doesn’t shrink it. Of course … Continue reading Automatically shrink your VM disk images when you delete files
