Uh, I've never played with alternatives before. Would someone care to
flesh out this proposal?
Okay, here we go:
/usr/bin/sensible-window-manager (or whatever) is a symlink to one of
the installed window managers. The symlink is managed by calling
update-alternatives. update-alternatives has the following interface:
update-alternatives --install window-manager \
/usr/X11R6/bin/sensible-window-manager /usr/X11R6/bin/twm 10
This sort of call is made from the window manager's postinst. It
makes a link from /usr/X11R6/bin/sensible-window-manager to
/etc/alternatives/window-manager. In turn,
/etc/alternatives/window-manager points to the currently installed
window manager with the highest priority, where 10 is the priority for
/usr/X11R6/bin/twm.
update-alternatives --remove window-manager /usr/X11R6/bin/twm
Called by the window manager's prerm, makes sure that the
/etc/alternative link doesn't point to that window manager, and
removes the link entirely if no window manager is installed any
longer.
Do you need more details?
