It looks like openwrt, though not sure how much they have done. Anyone has any insight?
Openbricks has evolved from the geexbox project, which was an extremely slick mini-distro for loading itself into RAM and watching DVDs back in about 2004ish. The build-system was well-engineered even back then.
It seems that they have realised they had quite a nice build system so they have split that out and made it into a project. The main developer gave a talk at FOSDEM ths year.
I'm not sure that the world actually needs any more embedded build systems based on kbuild (ptxdist, buildroot, yocto, openembedded is probably sufficient), but here is one more anyway. I haven't tried using it in its modern incarnation, but it looked good.
Wookey
