I don't think there is a portage option for that. Perhaps you could use schedtool? with 'schedtool -a' you can specify a list of cpus a proces may run on. > > If possible, I'd also like to limit the total disk bandwidth > consumption during emerge.

Is there an option that addresses this? perhaps ionice is the tool for that? -- Christer
