title: Reload XINITRC without restarting Xorg
body: <p>I have some simple scripts that allow me to change where certain versions of applications are used at run-time that are coded in to my .bashrc file.</p>
  
  <p>For example, let's say I have the 'cat' application. There are two versions, one in /test/working and another in /test/beta.</p>
  
  <p>If I run a bash command, "changer.sh", it changes the symbolic link in /bin/cat to point to either /test/beta/cat or /test/working/cat. When working in terminals and within Konsole or Xterm, this works fine.</p>
  
  <p>I also have a line in my .xinitrc so that X applications can see this environment variable as well, but there is a problem: it seems that Xorg/Xfree86 de-references the symbolic link when Xorg starts up, so, for the entire duration of my Xsession, "cat" is resolved as /test/working/cat, and never re-evaluates the symbolic link if it changes later on. It seems the only workaround at this time is to close and re-start Xorg every time I change this symbolic link. Is it possible to force Xorg to reload/re-parse my .xinitrc without having to restart it each time?</p>
  
  <p>Thanks!</p>
