Hi Folks,

Some clarity will follow on how we plan to deliver Addon repositories
like ResilientStorage, HighAvailability and NFV.

Because of Red Hat’s desire to develop Addons along with the next minor
release of RHEL our plan is to enable ResilientStorage and NFV in CentOS
Stream for direct consumption.

If you think a package belongs in another repository, we encourage you
to open a CentOS Stream bugzilla to discuss with RHEL maintainers:

https://bugzilla.redhat.com/enter_bug.cgi?product=Red%20Hat%20Enterprise%20Linux%208&version=CentOS%20Stream

We do not plan to expand the portfolio of Addons for CentOS Linux.

If there is a group of interested folks who wish to maintain extra
content built against CentOS Linux, you may apply for a Special Interest
Group: https://wiki.centos.org/SIGGuide

Cheers!
