We're working on a small NAS-like device. Very light weight, and targetting to consumers rather than businesses, so everything will be pretty simple. I'm currently working on getting a 2.6.x kernel up on the early boards. Once that's up and running, I'll be working on the rootfs. I've been doing a lot of checking as far as dependencies go, and I've got the libraries narrowed down substantially. We're also using the 2.2.x samba branch, since the 3.x branch requires a large number of libraries that we don't want to include. I've been ensuring that every binary going into the image is stripped so far as well. I guess I was kind of hoping that the gentoo embedded group was working with small root filesystem sizes, and whether or not there was a base layout package that would simply contain things like pre-populated /dev, and other absolutely essential sources like that. Are there any plans for such a package? Perhaps with makefiles that would leverage cross compilers to create a base system for target X on host Y? It would make embedded development incredibly easy with cross compilers and base layout packages of that sort ready to be emerged into /opt or something like that.
