I am working on build customized Fedora ISO live CDs images and I had a strange behavior here.
At first, I did the following procedure:
- Installed Fedora34 Workstation on my machine
- Installed livecd-tools
- Installed spin-kickstart
- Copied the directory /usr/share/spin-kickstart to my home directory
- Ran the following command:
sudo livecd-creator --verbose --config=fedora-live-security.ks --fslabel=SecuritySpin --cache=/var/cache/live
Everything when well. I could save the iso generated file to a pendrive and started the livecd.
But, then I did the following:
- Upgraded my operating system, using Gnome Software Update tool
- Run again the same livecd-creator command
The build process went well, similar to the previous one.
But in this case, when I loaded the pendrive, the system does not boot.
After some time, I have the error message “Failed to listen on udev kernel socket”.
Is there any explanation about why the new ISO fails to work after upgrading the host system?
