ivman + sudo

[wizardofos]

Hi

I've got Ivman installed to manage my system's HAL events, such as hardware plugging, media changing and ACPI.
I want Ivman to be able to write "ondemand" in my /sys/devices/system/cpu/cpu0/scaling_governor when I plug out the AC_Adapter of my laptop.
Manually I do it like this: "echo ondemand > ...". But I don't know how to write this command in /etc/sudoers.

greetings

Would you really need to add that to sudo if you define it in the system wide config file? If you define it there, then it will be run with root privilieges I would guess.

May I ask you how you've defined the acpi-stuff - maybe you can post your config file? thanks.

No, cause my systemwide IVMan runs with the privileges of 'ivman', a user added by portage. (btw: why does portage that?)
