I don't see anything there about needing to be on the same filesystem, just that the path is of the form /home/$user/snap. It says that having a home directory that isn't mounted at boot doesn't work, but that's different. Am I missing something?

I'm not sure why you'd need to symlink /home/ to another filesystem instead of just mounting that on /home/ directly, that's what I'm doing with root on ZFS and a separate dataset for /home/ with it's own mountpoint.

Snap also stores stuff in /var/snap, and that probably also has to live on the same filesystem.

Anyway, now I'm working around limitations in Snap instead of Snap working around its own limitations in certain circumstances. The fact that Snap shows weird behavior and illogical error messages in these cases tells me that Snap is not (yet) up to the task of fulfilling this rather fundamental role in my OS.
