Hi, I wanted to ask if there are any other documents applying to the CGL5.0 spec than CGL_5.0_Specification.pdf CGL_5.0_Registration_Template.xls AlpineLinux (a quite telco-like oss distro) is currently weeding out the kernel modules they deliver per default. I suggested we go through the CGL spec for a baseline since that way we have nice xls / pdf list to tick off. A few items from the signaling world that a real CGL distro would include will of course be overkill, still I think CGL is the best way to define a stable base for a kernel :) I just remember there was more different spec files during the 3.0 time. Will the above files do as a good starting point? Anything else you recommend?
