Describe the problem you're observing

When building a initramfs without systemd using dracut, the inclusion of the zfs module causes udev to break, endlessly printing System was booted without systemd as PID 1; can't operate..

Describe how to reproduce the problem

uefi="yes"
hostonly="yes"
machine_id="no"
dracutmodules="base bash rootfs-block i18n kernel-modules zfs shutdown"
kernel_cmdline="rd.break=pre-pivot"

the rootfs should be on a zpool.

Changing the rd.break to pre-mount does not trigger the messages yet, so it seems that the stages from cmdline all the way through initqueue are working, so it does not appear to be an issue with udevd/udevadm itself.
