Is `--filesystem=host` needed or just `--filesystem=home`?

See details in https://www.man7.org/linux/man-pages/man5/flatpak-metadata.5.html#FILE_FORMAT.

As far as I understand, Octave only needs access to the content in the user home dir and not the full host filesystem.

in an ideal world, the filechooser portal should be enough, but it won't be if you need drag and drop (filetransfer portal is barely implemented anywhere).

[travier]

Sure, I'm not suggesting you remove the access entirely, just that you restrict it to the home dir.

Strictly speaking, Octave doesn't need access to any filesystems, but this is provided as a service to the user. Since Octave is a flexible development environment, users like to be able to open files, link libraries, and run programs from anywhere on the host filesystem.

If there is a compelling reason to restrict the default filesystem access, then we can certainly comply.

Alright, seems like a valid reason.
