Anything is possible. The issue right now is the relationship between ryao and the udev team (at least me). I don't want to bore the list with the details, but ryao misunderstood some action (or lack of action) on my part as ignoring him. Samuli, myself and robbat2 are the udev team for gentoo. What I do not know is if ryao spoke to the other team members, but what I do know is that a private irc conversation months ago is fine, but, from my perspective, it would have made sure that I didn't lose track of things if bugs had been filed, and they were not, so that is the only reason I lost track of his concerns. I asked him several times about joining the udev team, but for whatever reason, he feels that starting this fork was the best option, and he has told me he can't stop it. I'm with gregkh on the separate /usr issue though. It isn't just udev that has issues when /usr is split off. I think the myth that udev is the only culprit came out of the April 2012 council meeting. I'm pretty sure that what I'm about to say will be dismissed by the supporters of separate /usr without an initramfs or without using the sep-usr option we now have in our busybox ebuild, but in truth, splitting / from /usr is broken another way that we have been ignoring for a decade. We have been getting around part of the issue by moving shared libraries from /usr/lib* to /lib* and using gen_usr_ldscript to make sure the linker knows what we have done with them. The other breakage is any program that reads data from /usr/share does not work right if / and /usr are split and that program starts in early boot. I don't know what else would have to be fixed off the top of my head, but I can tell you that locales/nls are broken for early boot without an initramfs if / and /usr are split. Basically, if we want separate /usr without an initramfs and we want to do it right, we have to create /share and start copying things from /usr/share/* to /share/* and patching code to support reading both locations, starting with gettext/NLS support. So here is the question I'll pose. Is it worth all of that extra work for us to support separate /usr correctly, or should we just tell everyone to start using initramfs or, if they don't want to use initramfs and they are just using plain filesystems, the busybox[sep-usr] option once all of the tools are stable? I used separate /usr for a long time here without an initramfs, but after studying why this was broken, I switched over to an initramfs, and have been running one for months, because that seems to be the cleanest way forward. There is one other issue right now, and I don't know what util-linux is doing with it since our bug hasn't been updated in some time [1]. William [1] https://bugs.gentoo.org/show_bug.cgi?id=410605
