I'm damn glad that Linus and Al appear to agree with the rest of us who value stability in re the ongoing udev trainwreck. I don't *want* a new init system, I don't want to have to make invasive changes to my system on every udev upgrade, I just want something that manages a hotplug /dev for simple cases like usb mass storage plugged in after boot, lets me customize it by adding symlinks, tweaking permissions and the like, and otherwise gets out of the way.
udev used to do this when gregkh maintained it and for a while after, but currently is so far from this that is just not true. The last udev release that added a feature that I actually valued was about 130, but since then almost every release has been terrifying and introduced heaps of incompatible changes for no reason other than that it can, many releases have required invasive changes to the way my system is booted and break backward compatibility so that if I try to downgrade after a successful upgrade *that* will fail to boot, it's halfway to mandating systemd usage... no no no, bring back a udev with maintainership that understands how boot-critical software should be maintained, please. (That is to say, carefully and with great attention paid to backward compatibility and break-free upgrades without the poor distributors and/or upgraders having to whip themselves into a frenzy to do it.)
(Yes, I know I can just run an old udev. That's what I'm doing. But running unmaintained older versions of critical software required for boot because you can't trust the maintainers not to break your boot on every release is not good. Not good at all. Among other things, eventually programs will presumably start requiring a newer libudev...)
