Hu? By my "customers" I figure you mean RHEL customers? They don't use
the newest, hottest upstream systemd versions, but a stabilized
version that made its way through Fedora and the RHEL QA
processes. Production distros generally should handle it that way I
guess, not only for systemd, but any other project.

Yes, we do feature work upstream, where else?

Well, fixing bugs is hard work. Release engineering means fixing
bugs. That's a lot of work, and I do a good chunk of it. Please, by
all means, join in, but don't claim it wouldn't be that much work. It
is! A lot! (And thankless work on top)

Well, if you follow our commit history you'll see that quite often we
delay stuff until after a release. For example, right now #9762,
#10495 have been delayed from before the last release that way...

Again. Step up if you want to have more systematic relase
management. You are invited! I'd very much appreciate if you do.

It's not "me" who has that really. It's a group of volunteers doing
that, like a lot in Open Source. They scractched their own itches. If
you want a more strict cadence, the scratch your own itches, too,
please step up, like the folks doing the stable series stepped up!

Well, we rebase all the time, it's not that easy...

Well, I can tell you I will wholeheartedly support anyone stepping up,
and taking over release management. Otherwise we'll just keep trying
our best like we currently do, which isn't good enough for you.

You know, I try to split my time between new work and bugfixing. I
simply don't won#t to get sucked into just the latter.

We can certainly repriotize things and more often declassify bugs
hitting more exotic cases as release-crtical, in order to come to a
more strigent release cadence I.e. more aggressively ignore bugs with
exotic archs, non-redhat distros, exotic desktops, exotic libcs, weird
drivers, yadda yadda, and leave them to be fixed by community
patches. But I doubt that is in your interest either, is it?
