ok, that was easy. whipped up a package in about 20 mins. I still need to figure out which commands are provided natively in the OS so that I don't replace any of them. (I was counting on gnexus for that). I noticed that pidof was one of them, but still need to look in /sbin /usr/bin /usr/sbin etc

I'm also thinking I should call this busybox-alt or busybox-opt to differentiate it from the nokia supplied one and use "replaces: busybox" in the control file.
