ondemand script doesn't set ignore_nice_load

Binary package hint: initscripts

I just upgraded to jaunty, and discovered that powernowd has been deprecated in favour of just using /etc/init.d/ondemand. That's fine, except that init script doesn't set ignore_nice_load, which on my system makes a big difference in power and heat savings (or at least it will again once #368809 is resolved).

My suggestion: add an /etc/default/ondemand that has a flag for enabling ignore_nice_load, since there seems to be some controversy over whether or not it's helpful. This way, it can be loaded by default (which, IMO, is the correct behaviour), but can also be easily disabled if people would rather turn it off.
