To be a bit more concrete:
I have a Debian Squeeze Linux machine with a web application that should become available all over the planet. Until now I had a bunch of resource consuming cronjobs each night (in Europe) without much impact on regional user experience. However now I cannot afford that the server gets slower at any time.
Is there a way to force all cron scripts (cron.daily etc.) to inherit a nice and ionice priority?
Thanks for contributing!
