| In which directory are you invoking dracut? From /usr/src/linux? Or from a directory where the "arch" folder does not exist? |

Looking at the code in dracut, there is some cd'ing going on that I think is the cause of this problem. Though I don't quite understand why I cannot reproduce it on my end, probably I am not hitting the problematic cd before objcopy is run.
Anyway, please test this patch for dracut and let me know if it resolves your problem: https://github.com/dracut-ng/dracut-ng/pull/834

Ext4, no fancy LVM/RAID setups.
FAT32 for the EFI partition.

From /usr/src/linux
Invoking it with $(pwd)/arch instead of just the relative path works, oddly enough.
Will do.

The new script seems to have fixed the issue!
Running the old one still yields the objcopy error, but the new one, pulled from https://github.com/Nowa-Ammerlaan/dracut-ng/tree/main, runs perfectly and yields a bootable working image for my system.
Parameters:
| Code: | | dracut --kver XXXX --kernel-image arch/x86/boot/bzImage --uefi --hostonly --fstab --kmoddir XXXX |
Thanks for the agility, there. I'm used to stuff like this taking at the very least, a few weeks.

Nope. Neither of them.
/boot/vmlinuz-XXXX doesn't exist because I'm using /efi as the EFI partition, and I'm building a UKI, so I don't get a separate kernel and initramfs. It's a single .efi file.
Now /lib/modules/XXXX/vmlinuz I don't know about. Why should it be there?
Regardless, the problem is solved with Nowa's patch. It seems to have been an issue within dracut with relative paths.

Because of "man 8 dracut": | Code: | --kernel-image <file>
Specifies the kernel image, which to include in the UEFI executable. The default is
/lib/modules/<KERNEL-VERSION>/vmlinuz or /boot/vmlinuz-<KERNEL-VERSION>. |

It exists if dist-kernels are used, we put a symlink there because the kernels rpm and deb packages have the kernel installed there and we like to have as much symmetry as possible in our gpkgs. You won't find this symlink for manually managed kernels.

Great! Thanks for testing! This fix has now been merged and will be in dracut 106+.

Actually, scratch that, this is quite a big problem so I backported my fix into version 105 which I pushed just now.

Thank you for solving.
Always glad to be of use.

Just out of curiosity/laziness (I could check the pull request, but meh): What exactly was the cause/solution? You mentioned "cd"s. Did you somehow keep track of the original working dir? It was an awfully fast fix, if so.

Once I realized the problem was likely one of the calls to cd, the solution became easy. At the beginning of the script we now store the working directory and later when the arguments are handled we use this stored pwd to convert relative paths to absolute paths.
