the zfs dependency in question is systemd-udev-settle.
Sep 1 17:49:20 xubuntu udevadm[1064]: systemd-udev-settle.service is deprecated. Please fix zfs-load-module.service, zfs-import-cache.service not to pull it in.

Opening tasks on systemd and zfsutils-linux, since these packages need to fight it out wrt the "deprecation".
And opening a task on the kernel, because a udevadm process that doesn't die with SIGKILL means it's hung in the kernel.
