• Make some changes in the tmp/work/ tree... In my case this was editing the source files in tmp/work/openslug-kernel-2.6.9-r1/linux-2.6.9/net/ipv4/...

This may be defined elsewhere, but I thought it would be helpful to mention it here. Basically, I've been trying to rundown the usbnet issues for OpenSlug and was adding some printk statements to the kernel for debugging. To perform this all I needed to do was:

• Edit the source files in tmp/work/openslug-kernel-2.6.9-r1/linux-2.6.9/net/ipv4/...
• Invalidate the timestamp files (by removing them): rm -f tmp/stamps/openslug-kernel-2.6.9-r1.do_compile
• bb openslug-image

This rebuilds the openslug-kernel from the compile stage and all the modules, ipkgs, and openslug-flashimage

This technique could be used for other stages also, like configure, or unpack, etc...
