User Feedback :: Missing cpp in image
When using /usr/X11R6/bin/xrdb, the process /usr/bin/cpp is used by default (hardcoded in process) but is not present within DSL image. Although there is an option to not use cpp, this is a drawback.
I suggest adding cpp to the image.
DSL does not use Xfree86 or Xorg.
We use the Kdrive TinyX server.
