Some changes to the installed XFree86 directory structure have been
implemented for 4.0.
change is a modified search path for the X
XF86Config file. The details of this can be found
in the XF86Config manual page. The other main change is moving
most of the run-time configuration files to
symbolic links in the old
/usr/X11R6/lib/X11 location pointing
to the new location. Some run-time generated files are now located
under the appropriate subdirectories of
/var, again with the
relevant symbolic links in the old location.
