Or, install the script as an init script, and have it look at uname, or /proc/version, or something to pick it automatically, before the display manager starts (or add it to that init script). Something like: uname -r |grep -q rt && ln -sf xorg.conf.rt xorg.conf || \ ln -sf xorg.conf.std xorg.conf With pathnames, I guess.
