I'm fairly sure the stock debian install includes menu-xdg (menu-xdg_0.2.3_all.deb). "dpkg --contents " for this .deb show that it includes /etc/menu-methods/xdg-desktop-entry-spec-sessions. I believe it is this file that creates the additional .desktop file.
The README in /etc/menu-methods states : "update-menus runs all files in this directory, passing it all menuentries to install on stdin." The fvwm.postinst script calls upon update-menus via: # Ensure the menu system is updated [ ! -x /usr/bin/update-menus ] || /usr/bin/update-menus so, what I think is that the file /usr/share/xsessions/Fvwm.desktop that is included with the fvwm .deb is redundant and probably not required as update-menus creates a .desktop entry in /var/lib/menu-xdg/xsessions/ any comments?
