For upcoming releases of Xorg, you can safely remove all the code in Xsetup_0 (http://dev.gentoo.org/~spyderous/xorg-x11/patchsets/6.8.1.903/files/Xsetup_0) That code was used for kde-3.1, which is not in the tree anymore. I suppose Xsetup_0 should stay as an empty file (containing only the headers).
My proposed change is to stop installing one from our filesdir and to start installing upstream's version, which is an uncommented line 3 of this, with everything else deleted. Sound good?
It would not matter for us, since kdm does not use Xsetup_0 anyway... I think only xdm uses it (and gdm, too? I'm not sure)
Do you guys use /etc/X11/xdm/Xsetup_0 at all?
I'm pretty sure GDM doesn't use it.
Removed in 6.8.2-r2 and 6.8.99.13. Sorry for the delay.
