[OE-core] [PATCH] systemd: add usrmerge to REQUIRED_DISTRO_FEATURES
From: Luca Boccassi
Support for unmerged-usr is deprecated upstream, taints the system and
has been removed for v255 (next release).
Enforce building merged-usr images when using systemd. This allows one
release cycle where it can be tested for any remaining issue, and can
still be overridden, before it stops working completely.
Signed-off-by: Luca Boccassi

Time to resurrect this. Support for unmerged-usr has been removed and
will no longer be available starting with v255. Better to get started
now with the enforcement, so that things can be worked out while it is
still possible to override it.

FYI, we now have a tentative timeline: first release of H2 2023 will
drop support for split-usr and unmerged-usr:

Re: [OE-core] [PATCH] systemd: add usrmerge to REQUIRED_DISTRO_FEATURES
It’s been in the news that lennart has left red hat and moved to Microsoft recently and will continue with systemd there. Which is rather worrying, as Microsoft by and large is only interested In linux on azure or wsl. I can help iron out the issues once we have a list. Alex On Wed 13.

This is not going to help systemd's reputation. Basically, we have to do what Fedora does and look as we're told to, which does go against our configurability objective. We already have tensions around musl and this will further demonstrate our direction and systemd's are not aligned. I do understand why systemd is doing what it is doing and that it really doesn't care about our use cases. That doesn't stop some users wanting it (but also wanting other things we have like musl).

We've been running this configuration internally for ~3 years in our
Yocto downstream, never seen any issue, not even at the beginning, it
just worked.
Nowadays most major distros have switched over, Gentoo's the other one
left but it's planned for this year.
Any issues in upstream softwares should have been fixed years ago when
Fedora started the process.
So hopefully it shouldn't be too bad?

It's not urgent. But the build-time warning has been in place for a
couple of years now, you should have already seen it.
The runtime is a taint flag in 'systemctl status', and was introduced
in the most recent release.
There is no timeline as of now for dropping legacy compat code and
configuration, as the runtime taint was just added.
Certainly won't be this year. I've been doing the rounds ensuring
everyone who hasn't switched already is aware with plenty of time to
spare.

It is a done deal as far as we are concerned upstream, matter of
'when' not 'if'.

The configuration is yocto-autobuilder-helper but the best place to
start is probably the poky-altcfg distro config.
Once we change that we'll have to run through the testing, see how much
breaks and then find someone to try and fix any issues if/as needed.
There is a lot of work just in pulling things together for testing and
triaging the result and I'm depressed it will probably end up on my
plate when I personally disagree with the decision.
I was asked earlier today if we should just make the systemd include
files force usrmerge on. The challenge is that OE/YP give users choice
to configure their system how they wish, we don't just force
configurations upon them. Or only real option is therefore to throw
errors and have them decide what to do (which basically amounts to
submitting to the upstream decision).
> Also is a deprecation notification needed? How is it handled usually?
Do we have time for such a notification or are we in the situation
where we just throw errors to the user and let them agree to the
usrmerge change? The timescale is unclear but if the systems are
already throwing deprecation warnings at runtime, this isn't a good
experience for our users.
> Aside from process details, I assume there's no problem with doing the

There is, but it appears a done deal which we just have to accept so
I'm trying not to start a discussion which I don't think can go
anywhere productive. If this isn't a done deal, then let me know as
that would be different.

Richard

Yes I was expecting there would be these kind of issues, the purpose
of sending this was mainly to find out about them.
So where are these configurations stored? How can we get them updated?
Also is a deprecation notification needed? How is it handled usually?
Aside from process details, I assume there's no problem with doing the
change in principle?
Thanks!

Given none of our systemd testing on the autobuilder is done under
usrmerge and we've never mentioned this requirement to any of our
userbase before, this is going to come as a bit of a surprise to
people. The above change will break the autobuilder as things stand :(.

[OE-core] [PATCH] systemd: add usrmerge to REQUIRED_DISTRO_FEATURES
From: Luca Boccassi
Support for unmerged-usr is deprecated upstream, taints the system and will be
removed in the near future.
Enforce building merged-usr images when using systemd.
Signed-off-by: Luca Boccassi
---
We intend to deprecate unmerged-usr at some point, and we are doing the
rounds ensuring distros are moving along so that there are no surprises
when the time comes.
