New issue by adrian-bl on void-packages repository

https://github.com/void-linux/void-packages/issues/37667

Description:
### Is this a new report?

Yes

### System Info

Void 5.18.4_1 x86_64 GenuineIntel uptodate rFFF

### Package(s) Affected

zfs-2.1.5_1

### Does a report exist for this bug with the project's home (upstream) and/or another distro?

_No response_

### Expected behaviour

The system boots

### Actual behaviour

After upgrading 2 systems from ZFS 2.1.4 to 2.1.5, both systems fail to boot as dracut complains about not being able to mount the rootfs.

Note that ZFS is *not* used as rootfs: one system uses ext4, the other btrfs.

### Steps to reproduce

1. Have a non root-on-zfs system
2. Install zfs-2.1.5_1
3. Reboot -> system will fail to startup
