+1, there is a lot of things we need to improve in OST, the network suite
is a good example of going forward with PyTest, we have other idea for
improvements like splitting the suites into multiple projects using a new
feature in std-ci,
dropping the reposync file or making it optional ( actually ovirt-demo-tool
is already doing that, using release rpms ).

If there are more ideas, we can consider doing an infra hackathon where we
can focus in improving infrastructure and moving to PyTest most of the
tests ( at least in master ) .

We need to think on a new design for it which includes scalability and
multiple maintainers, the requirements and usage has changed significantly
over the years,
I also don't have an easy solution for it, yet at least.

This could have been better if the single OST maintainer could be part of
the planning and also participate and give feedback and assistance,
unfourtunately it was decided to do the hackhaton without him present.
I agree we need to improve our contribution guide, and work has started
towards it, but any specific feedback or tickets on what can be improved
will surely help.

This is very close to be much better, we're 1-2 weeks away from implemeting
a new feature in STD CI V2 which will allow us to replace the existing
'change resolver' and eventually run all suites in check-patch in parallel,
dramatically reducing runtime.

Its not that its not smart, its by design, repoman uses "only-latest"
option to get the first RPM he finds from the repos, I'm pretty sure there
was a good reason behind it when it was written a few years ago, I'll try
to remember and update.
In any case, the relevant patch where this was needed had a different
problem with dynamic replacement of repos which we need to think on a
solution for.
