zfs: udevadm[2006]: systemd-udev-settle.service is deprecated. Please fix zfs-import-${pool}.service not to pull it in.

[nagisa]

Describe the bug

systemd/udevadm complains about zfs-import-* services using deprecated features. In journalctl you can see the message from the title being emitted during an early boot.

Nothing is broken quite yet, but it may break sooner or later if left untreated. And filesystems are sirious stuff™, so we better stay on top of it.

Steps To Reproduce

Steps to reproduce the behavior:

1. Set up ZFS using NixOS modules, and boot
2. Check journalctl.

Expected behavior

Using ZFS does not result in deprecation warnings in journal
