[CentOS-devel] CentOS Linux 8 and SIGs content removal plan (please read)

As you’re all aware, and per https://www.centos.org/centos-linux-eol/ , 
CentOS Linux 8 is going EOL end of this month, and content will just 
remain available on mirror network until January 31st.

After that date, CentOS Linux 8 repositories will be removed from mirror 
network, and mirrorlist will start answering “invalid release”, so no 
way to easily install any rpm component.

But what about SIGs content that was built for/against CentOS Linux 8 ? 
(basically other repositories that you can see under 
http://mirror.centos.org/centos/8/ but that aren’t coming from centos 
linux 8 distro itself ?

As soon as CentOS Stream 8 was announced, we offered the possibility to 
all SIGs to opt-in and build for/against Stream 8, and so have their 
repositories automatically pushed to 
http://mirror.centos.org/centos/8-stream , as it was for /8/ .

Most of the SIGs opted at that time to build in parallel for 8 and 
8-stream, while some decided to just start building against/for 8-stream 
directly (and of course content built on 8-stream *should* just work 
fine, and reverse is also true)

But some months ago, community members asked 
(https://pagure.io/centos-infra/issue/400) if that was possible to 
continue building against/for el8, but so switching buildroot from 
centos 8 to RHEL 8, which was worked on and is now available.

What does that mean for you, SIGs ?

If you want (opt-in and so optional) continue to build for el8, just 
create a ticket on https://pagure.io/centos-infra/issues to ask your 
tags to build against RHEL 8 instead of CentOS Linux 8. You can do that 
whenever you want but before (for obvious reasons) end of January 2022

What if you don’t opt-in ? You SIG content will removed from mirror 
network, at the same time as CentOS Linux 8 content.

So to recap :

  * End of january, *all* repositories listed under 
http://mirror.centos.org/centos/8/ will be removed (except for SIGs that 
opted-in for the ‘switch to RHEL 8 buildroot’ plan)
  * mirrorlist.centos.org will also start answering ‘invalid repo’ for 
SIG content, as it will be for CentOS Linux 8 itself
  * All SIGs tags for 8 will be locked down (except for SIGs that 
opted-in for the ‘switch to RHEL 8 buildroot’ plan) so no way to just 
tag-build (and so push anything) out
