SNAP_REAL_HOME is kinda buggy

Answering one by one.

dosbox-staging and other snaps that I tested are snaps with grade: strict Means they are non-classic

Didn’t understand this question correctly? Can you make me that out?

Yes this is the case for non-classic snaps.

I have two main reasons for this,

  1. Apps where the user needs to pick some file from the file-chooser, if the HOME folder takes them to somewhere else, then it’ll be very confusing for them that to access files saved in the /home/$USER, they need to click on their username on the top bar of the file manager.
  2. I am recently snapping an app which saves the config file of my current desktop as a backup. And when needed, they can restore them. The app is savedesktop I am talking about. It needs the correct home path for that purpose. Also, currently the portal is not working with snaps, so, this is the only alternative left, which needs to bug free for now. This is the forum post I’m talking about.
