Custom home folder

Problem

When running the program inside a flatpak sandbox, selecting a custom home-folder will result in a home path similar to /run/user/1000/doc/381947/your-folder.

That's a virtual folder, returned by the flatpak file chooser portal. It can't be used directly by distrobox.

Solution

DistroShelf already tries to resolve the real underlying folder by using the command getfattr. If you have that command installed, you shouldn't have any problem.

If you don't want to install that command, you must grant DistroShelf access to the whole filesystem. You can do so using a program like FlatSeal.
