# Functions to convert isolinux config to allow selection of desktop
# environment for certain images.
# All config file names need to be in 8.3 format!
# For that reason files that get a "desktop" postfix are renamed as
# follows: adtxt->at, adgtk->ag.
# With two characters (dt) for the postfix this will leave as maximum
# for example: amdtxtdt.cfg or amdatdt.cfg.
