[arch-general] XDG variables no longer set

[Robbie Smith]

For some reason, after my last reboot (a kernel update), none of the XDG 
variables[1] (such as $XDG_CONFIG_HOME) are being set, which broke a lot 
of my configuration, as I rely on those in scripts.

I was able to fix it by writing a script[2] to drop in /etc/profile.d/ 
that would create those directories and export the variables as 
required, but what I want to know is why they broke in the first place.

Has anyone else experienced this?

[2] Like this (taken from /etc/xdg/xfce4/xinitrc) :
     #!/bin/sh
     # $XDG_CONFIG_HOME defines the base directory relative to which
     # user specific configuration files should be stored. If
     # $XDG_CONFIG_HOME is either not set or empty, a default equal to
     # $HOME/.config should be used.
     if test "x$XDG_CONFIG_HOME" = "x" ; then
         XDG_CONFIG_HOME=$HOME/.config
         export XDG_CONFIG_HOME
     fi
     [ -d "$XDG_CONFIG_HOME" ] || mkdir "$XDG_CONFIG_HOME"
