I don't think the current status quo would be a good starting point for that. Before submitting I saw CONFIG_PATCH=y, which is a lot more of a "Why would I ever need this on an embedded device?". Not saying that you are wrong, but the starting point should be a review of the current config. > Customizing busybox for what you're trying to _do_ with a custom setup > is one of those top 5 TODO items with making a cut down image and > customizing the kernel config.

E.g. 0.45 MB for a standalone tar is much when the little functionality you actually need is also provided by the busybox applet. Plus there is also the convenience point that most of the tools you need are already installed just by adding busybox with the default config. > Tom cu Adrian -- "Is there not promise of rain?"
