simple-ubuntu-installer VS zsys

I use this to automate Ubuntu zfs installation. https://github.com/prabirshrestha/simple-ubuntu-installer

From this bug report on github, here is a clear explanation of the problem:

This is a good thing for ZFS and public perception of ZFS. Ubuntu has made some very poor choices with how they've integrated ZFS -

* zsys has both implementation and design flaws. They utilize two zpools - one with limited feature flags that GRUB can use and one general pool, and then try to tightly couple datasets between those two pools while coordinating snapshots. zsys routinely runs a system out of space due to not cleaning up snapshots. It's been known to destroy user data as well.

Example: https://github.com/ubuntu/zsys/issues/155

Heard of it, but I have no idea how it works and if I must install ubuntu server completely new. After a bit googling it seems dead? “It seems the project has been dead for months now. What going on?” https://github.com/ubuntu/zsys/issues/213

Ubuntu isn't my preferred OS these days, but I've had excellent experiences with it's ZFS root installs as well as it's included zsys: https://github.com/ubuntu/zsys

Re: things I've actually dealt with, see -- #172

I even filed a very polite GH issue about how zsys doesn't handle other systems/sanoid snapshots well, to which I got no response. However, a previous response to a user with the same issue was "Turn that other method of snapshot-ing off and delete your other snapshots" which, I'm sorry, just doesn't make any sense to say to any ZFS user -- "Pound sand and delete some of your data, then maybe it will work." Say what?

https://github.com/ubuntu/zsys/issues/112 - This could be an incompatibility with the way docker stores volumes, but this looks like it should've been fixed a while ago?
