The generic Red Hat Xsession script is now owned by the xorg-x11-xinit
package, which contains:

Provides: xinitrc = 5.0.0-1

The reason it was kept in the xinit package instead of being coupled with
xdm is twofold:

1) The 'xinitrc' and 'Xsession' scripts used to share a lot of code which
   got out of sync very often as a bugfix was applied to one file, but not
   the other.  I split out their common code into 'xinitrc-common' which
   both of them source.  It is easiest to maintain them in one package
   rather than two.

2) I believe both gdm and kdm use xdm's Xsession script.  It is better to
   have it in the xinit package, so that gdm/kdm do not have to have a
   hard dependency on xdm for the script to be installed.

That coupled with the above virtual provide I mentioned, means gdm/kdm
should work fine by doing 'Requires: xinitrc', at least for the time
being.

Note however, that the monolithic tree with xinitrc, has a number of files
with hard coded paths set in /usr/X11R6, whereas the new xorg-x11-xinit
package has all of the paths set to /usr.  If this is a problem for gdm
or kdm, I can review the scripts and have them check /usr/bin first, and
fall back to looking in /usr/X11R6.
