  - huge work around the mess that is gnome-terminal-server
  - install two different desktop files to /usr/share/byobu/desktops/*
  - in postinst, symlink the correct one into /usr/share/applications
  - clean up that conditionally installed symlink in postinst
  - suggest gnome-terminal package, as our new desktop file hardcodes
    gnome-terminal (this kind of sucks)
  - in byobu.desktop, exec gnome-terminal with a --app-id hint, and
    drop the Terminal=true, as gnome-terminal will take care of that
  - install a dbus service, as new gnome-terminal expects to launch
    via dbus
  - fqdn namespace that service to us.kirkland.terminals.byobu
    + this is stupid, btw
