I imagine it becomes pretty important to define what use-cases it is intended to cover. What set of tools are important in a verification image? An awful lot of the time all I want is an initrd with busybox. The one I'm currently using weighs in at only 2.1M, and for my purposes I don't want anything larger. (But I'm also do silly fringe things like boot a system without touching any form of storage). :-) OTOH, I'm beginning to use autotest a lot, and python on the target is a requirement for installing test cases, which kind of blows 2.1M out of the water. g. _______________________________________________ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev
