Thank you very much. I'd gladly entertain a pull request if you'd like to integrate it. I'm not doing much in the way of active development on the script until I have either (or both) of my machines operational again; they're almost there, but I'm a sticking point with the 3.3.8 kernel, got past that, and have now discovered that stable genkernel and stable gentoo-sources don't play well together. (Because stable genkernel is using a slightly older version of busybox which doesn't know about some moved kernel header files). That stuff is slowly moving on b.g.o, and I'm slowly working around at home. It's only a matter of time, of which nobody seems to have enough... -- :wq
