Bug ID: 56310
           Summary: Isolate Filesystem from Wine
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]

      Distribution: ---

## Background

Currently, Wine by default allows Windows programs full access to the Linux
file system.

This, is of course inherently insecure and exposes the system to being
vulnerable to malware.

This is also not ideal for Atomic Systems such as Fedora GNOME Atomic, in which
Wine is installed via Flatpak.

## Solution

Isolate Wine from the filesystem by not mounting all drives to Wine.

## Side effects

The User can no longer access drives and storage outside of wine by default.

## Side effect solution

There are a few methods to solving this issue.

- Provide an option in the Wine File Picker to open the XDG File Chooser
instead. Documentation here:
https://flatpak.github.io/xdg-desktop-portal/docs/doc-org.freedesktop.portal...
- Provide an option to select directories in Wine Config. (Possible blocker is
that there does not seem to be a way currently to have persistent access to a
directory)
- File Manager integration, providing a "Wine" or "Windows" section similar to
how NextCloud does with it's nautilus integration.
