I’m having some trouble building a custom Fedora spin using Lorax on Fedora 42. The build completes successfully, but when trying to boot the Live image, it fails with an error about an executable file not being found.
The specific error is:
initrd-parse-etc.service: Unable to locate executable ‘/usr/lib/systemd/systemd-sysroot-fstab-check’: No such file or directory
initrd-parse-etc.service: Failed at step EXEC spawning /usr/lib/systemd/systemd-sysroot-fstab-check: No such file or directory
I took a closer look at the initrd image from the ISO, and it appears that symlinks are not being created for the fstab-check executable.
Specifically, on Fedora 42, I see:
lsinitrd ./out/images/pxeboot/initrd.img | grep fstab-
-rwxr-xr-x 1 root root 57888 Feb 16 01:00 usr/lib/systemd/system-generators/systemd-fstab-generator
But on Fedora 41, I see:
lsinitrd ./out/images/pxeboot/initrd.img | grep fstab-
lrwxrwxrwx 1 root root 41 Nov 27 01:00 usr/lib/systemd/systemd-sysroot-fstab-check → system-generators/systemd-fstab-generator
-rwxr-xr-x 1 root root 62168 Nov 27 01:00 usr/lib/systemd/system-generators/systemd-fstab-generator
As you can see, the symlink is present on Fedora 41 but not on Fedora 42. There appear to even more missing symlinks.
Anyone encountered a similar issue when building custom 42 images? Any ideas on how to resolve this? Not sure if the problem is lorax(tried 41 version 42) or dracut or something else.
I am using the following to build the iso.
livemedia-creator --make-iso --no-virt --nomacboot --resultdir=./out --iso-name=fedora.iso --ks=./fedora-live-workstation.ks --releasever=42 --project=“Fedora” --app-name=“Fedora” --dracut-arg=“–xz” --dracut-arg=“–no-hostonly” --dracut-arg=“–no-early-microcode” --dracut-arg=“–add livenet dmsquash-live dmsquash-live-ntfs convertfs pollcdrom qemu qemu-net”
