Sure, I can do that. My aim for override those in a bbappend is just for
development purposes and nothing I plan to use in production or push in
public. My way of working when I realized this was to build latest
master of systemd that had a bunch of patches that I would like to test.
To do that I needed to change git repo to systemd.git. When tested I
plan to backport relevant patches that I need to add to current systemd
version in oe-core to my local layer until next systemd release. Then I
thought this could simplify things for more people. But I'm fine if this
is not accepted for upstream and I can work around that.
We had a related discussion recently regarding mesa, where there is a
similar desire to 'reuse' the recipe from core as much as possible but
build from a different revision. Typically this would be done by
having some kind of common .inc file (systemd.inc in this case), and
then adding the missing parts in a custom .bb that includes the .inc
across layers (bitbake allows this). No promises about keeping things
in .inc compatible with whatever happens in custom layers though.
This opened my eyes for the way systemd recipes are built up in oe-core.
It seems a bit the other way around. systemd.inc contains almost only
version information. systemd_251.4.bb is huge and contains a lot of
thing that I think can be shared among versions. If it had been the
other way around it had been easy to have a systemd_git.bb, including
systemd.inc, in my local layer (or upstream if desired) that build
systemd main branch. What do you think of that? Is is worth working on
such a patch? Or are there reasons for that setup?
Another option is to use the devupstream class, and there are examples
in oe-core for it. Would that work for you?
I'll manage this but thanks for the tip about devupstream class.
Best regards,
