Just so. We have the older fork that we're trying to port forward. If people have changes as we do that, it sure would be nice to have them go through us rather than create more conflict with the main tree. I don't need to have a new set of conflicts with main because someone thought that it would be a good idea to move the space before or after the '(' or after in a bunch of files. It's just extra work if I have to do it as part of the merging. Better that goes into the top of our queue so it's managed and easy and a click on github than another half hour I have to spend sorting that out when I'd rather be sorting out the substantial change that go on upstream in other areas that legitimately do make things much better. We talked about all this in the above thread, I thought, and I thought it was all settled, so I was rather surprised to wake up to this thread this morning. > > Marking the subsystem as maintained isn't saying the current code is > great, > > just that there is someone committed to improving it hereafter. > > OK, thank Thomas / Daniel for explaining and referring to the "BSD-user > plans" (which I didn't notice earlier). > > Warner, what about mentioning your plans here in this patch? > Where is there room in the MAINTAINERS file for that?

Why invent something new just to make it harder for me to get things into the tree? There's already the tiered maintainer stuff, and I'm trying to get our stuff that turn the current bsd-user that's crap into something that's quite solid. The plans are to get our changes upstream so there's no daylight between what we do and what's upstream, except for the newest system calls that are being implemented just after they enter FreeBSD. We have a bunch of changes that make bsd-user able to build tens of thousands of packages more or less natively (the setup is a hybrid environment where the compilers are cross compilers, but everything built is native and run in emulation). I tried getting one big omnibus patch together, but qemu's head is moving too fast, so those plans failed to ever reach the tip of the tree. In discussions referenced in this thread, people suggested I submit changes to the MAINTAINER stuff as a signal moving forward. I've submitted other patches as well to get things going (those are already in). I plan on submitting more, but wanted to get the simple stuff ironed out first. QEMU's workflow is utterly alien to me, to be honest, but I wanted to be a good citizen and learn on the basics before submitting things that were harder to do and/or explain. Anyway, I'm trying to learn the local customs here. I'm unsure what the next step here is. Can someone explicitly tell me that? I thought all these preliminaries were already sorted out. Warner
