You can comment on it at https://github.com/freebsd/fcp/pull/6 but the FCP number may change since the allocation isn't official. I've created this on the belief that everybody here is either agnostic or fully supports this path. The FCP tries to enumerate the work and impact, but currently needs your help to flesh things out. I've done a first pass, but it's lame still. This is one of the first FCPs, so I'm going to use it a little as test case for the larger thing. There will be bumps. Feels may get bruised, but if so accept my apologies and help me do better in the future. I cc'd the re@ as a heads up that this may be coming down the pike and that discussions so far have been super hand-wavey on the RE@ side of things. I'd like to know what the actual impact will be so we can document it. At this stage, it's still in the draft stage and nothing is certain. This is my call for feedback, but call it 'pre-feedback' if I read FCP-0 wrong and am doing it wrong :) My gut tells me that to make my doc better, do it on the pull request. To raise serious issues that need to be discussed, reply to this message. To talk about the many flavors of Rpi, about unified releases, 32-bit ports to A-53, or any other odd tangents, please do that in arm@, but I'd humbly request a new subject. Comments? Warner
