WindowServer needs persistent access to a few things:
- /res (for themes, fonts, cursors, apps, wallpapers, etc.)
- /etc/passwd (for username lookup, not sure this is actually needed..)
- /home/anon/WindowManager.ini (FIXME: this should not be hard-coded..)
These things are unveiled temporarily, and then dropped:
- /tmp (for setting up sockets)
- /dev (for opening input and framebuffer devices)
This leaves WindowServer running with a very limited view of the file
system, how neat is that!
