Thanks for giving this a good look. I can verify now that the script is
doing its job. Something else is overwriting the file again after that.
Given the nature of the overwrite, I have to think that I must have set
in place whatever is doing the damage. Probably some earlier
troubleshooting attempt which I did not record and have now forgotten.
If I can't remember then I suppose I'll have to look through every
location where something can start from in an LTSP client bootup.
