You make an excellent point about single-point-of-failure. It wouldn't
necessarily have to be a new daemon. ZFS already has a daemon, so this
could just be additional functionality.
I've pointed Brian Behlendorf (the upstream ZFS-on-Linux lead developer)
to this bug report. It'd be nice to get som

I see, thanks. (Sorry, I'm just familiar with btrfs and subvolumes,
and they work differently). So I see how putting this into
local-fs.target in parallel with the fstab mounts makes sense.

Yes, each filesystem has a "mountpoint" property. This can be set directly,
and is also inherited automatically. For example, I have rpool's mountpoint set
to / and then rpool/home automatically inherits /home

Ah, I see. So do file systems from ZFS have a separate equ
@smoser: If this is a fresh install with no zpools, you shouldn't have a
zpool.cache file, and so your chain should have zfs-import-scan.service,
not zfs-import-cache.service. You'd still have the same problem, I
expect, but that detail is a bit worrisome.

Correct. The root pool (with all of its filesystems) is handled in the initrd.

@pitti: zfs-import-cache.service doesn't "load the ZFS cache". It
imports zpools which are listed in the /etc/zfs/zpool.cache file. It is
conditioned (ConditionPathExists) on the existence of
/etc/zfs/zpool.cache. It seems to me that upstream ZoL is tending to
deprecate the zpool.cache file.

There is some angles of attack here:

└─systemd-udev-settle.service @494ms +1min 275ms
This is a case of "you asked for it, you got it", really. udev-settle is
a workaround for old software that wasn't written with hotplugging in
mind. It's 2016, and

So:
a.) zfs-import-cache.service is 'After systemd-udev-settle.service'
b.) cloud-init installs /lib/udev/rules.d/79-cloud-init-net-wait.rules which
uses IMPORT of /lib/udev/cloud-init-wait to block network device add events
until cloud-init-local has written networking configuration
