Interesting, I didn't notice that the scripts in github already had
the "After=cryptsetup.target" added. I'm using zfsonlinux release
0.6.3, which didn't have those lines (added 26-jul-2014 to the repo),
and spent the better part of a day trying to figure out what to add,
and winding up with "Wants=cryptsetup.target" and
"After=cryptsetup.target" which I added to my local copies.

# systemctl show -p Before,After,Wants,Requires,WantedBy,RequiredBy
zfs-import-cache
Requires=systemd-udev-settle.service
Wants=cryptsetup.target
RequiredBy=
WantedBy=zfs-mount.service
Before=zed.service zfs-mount.service
After=systemd-udev-settle.service cryptsetup.target systemd-journald.socket


I need to set up a second machine or a VM to experiment on, because I
don't want to keep rebooting the production one.
