1. That is correct! We looked at different options on how to build the ISO (mkisofs is really cool but doesn’t play nice with the NixOS installer image), and ultimately went with building it on a Nix server.
2. Apologies for that, that was a leftover from when we were trying to gauge how many people were downloading ISOs when we showcased it to a club on campus yesterday. That has now been removed.

Thanks for the heads up on mobile! We agree, certainly everything needs more work, but full disclosure, we are all full time students and working on this project on the side. :)

Ditto on using TrueNAS scale! That is how I got a friend started on selfhosting, and they love the built in App Store!
