Bug: initrd-zfs-generator creates self-referential symlinks causing boot failure

[MrLutik]

Summary

The initrd-zfs-generator in sd-zfs creates broken symlinks in /run/systemd/generator/initrd-root-device.target.wants/, causing systemd to fail with "Too many levels of symbolic links" during boot. This prevents ZFS pools from being imported and the root dataset from being mounted.

Affected Repository

• Upstream: https://github.com/dasJ/sd-zfs
• AUR package: mkinitcpio-sd-zfs

Problem Description

When the generator creates symlinks in .wants/ directories, it creates them pointing to themselves instead of using relative paths:

Current (broken):

zfs-import-cache.service -> zfs-import-cache.service

Expected (correct):

zfs-import-cache.service -> ../zfs-import-cache.service

Symptoms

• systemd error: Too many levels of symbolic links
• zfs-import-cache.service never runs
• ZFS pool import fails
• Root dataset cannot be mounted
• System fails to boot

Environment

• OS: Arch Linux
• Kernel: 6.17.9-arch1-1
• ZFS: 2.3.5
• Package: mkinitcpio-sd-zfs (AUR)
