It looks like a tool that automatically generates systemd units
to handle mounting of ZFS file systems (on the original Solaris
ZFS is quite un-UNIX-y in it's behaviour regarding mounting,
simply creating a new ZFS file system will mount it, by default
below it's parent file system, and mount points are not detemined
by /etc/fstab but managed in the file system itself, by properties).
As all the infrastructure doing this is missing in Linux he wrote
this tool to emulate the behaviour.
It's one of the things that look weird if reading about it but
is quite fabulous once one gets used to it. ZFS has several of
those things hidden inside it.
Unlike chess, Mornington Crescent takes a lifetime to learn the rules,
and 5 minutes to master.
