You are supposed to use /var/home/user instead of /home/user in your paths, scripts, etc (or /var/$HOME). Im not certain on the why but iirc its because on immutable systems only /var is writable so anything writable has to be under it.

Id say just recommend Photon. It works well on both mobile and desktop. I love voyager but two very different uis is going to confuse new users.
