First I would apologize there are some unreasonable stuff in our build due to
historic reason.

Could you point me which tarball you mentioned? I don't think it's for any
purpose,
it may by just a mistake.

We used to encounter a bug that CloudStack UI went mad because these cache.
What's elegant way to solve such sort of problem?

This should be a bug. yes we should do it in our cloud-setup-management script
instead of hacking limit.conf. I will file a bug for this. Thanks

Do you mean waf will automatically install dependencies packages during RPM
build if
try-build was failed? Yes we can do it in a better way. If it's exact problem
you mentioned,
I can file a bug for this

Thank Robert for working on this. By chance I used to play OBS for a short time,
It's a nice tool. I like the feature that triggers a new build for a package
when one of its dependencies
updated. Please feel free to input your advices making CloudStack elegantly
build in OBS, I will
work with our dedicated build engineer to make that happen. Patches are always
welcome as well.
Thank you.
