Thanks, but no: I don't understand anything of the code in the sources:
So I'll mess with stuff I understand, and keep my hands off the rest
of it .. And, yes, I also didn't quite get so far on how to adjust
some new script safely to the scripts already being in /etc/power/ ...
So I'll simply wait and hope that the kernel folks working for IBM,
RedHat etc. will fix the problem that results from the new feature with
the extra console for sleep mode:
This bug will be rather annoying in production environments where
people would leave for some period of time their office chairs,
vlocking their computers, and trying to get the machine into sleep
mode -- wondering that it doesn't work as it did in 2.4 ... :)
3 months, or sooner, and this bug will be fixed. I'd bet ... :)
Or that's what I'd hope at least ... :)
PS: With Google I could not find the thread mentioned above: Did you?
Thanks for your time, Matthias
Best Regards
Wolfgang
