Hi, this is not really my job, but I don't mind ruffling a few feathers if I need to.
RHEL/CentOS 7.5 is probably around the corner. This would be an excellent time to remove any EOL software you may have floating around on mirror.centos.org. Unless otherwise specified, any SIG content under 7.4 will be copied over to 7,5.
I'd imagine that for example openstack-newton could be dropped because it went EOL in 2017-10-25. Is there some other content that could be dropped?
If SIGs want to drop something at 7.5 release time, please let hughesjr know. Filing a bug would be one way to do that. Content can be removed either by directory name, or by individual package names.
You should also communicate to your users in advance that the EOL packages will disappear, and if necessary, instruct them to migrate to a newer supported version. Having instructions for that procedure published somewhere would be nice.
The old content under 7.4.1708, including any EOL content, will be archived to vault.centos.org, and that content will be available in the vault indefinitely. The 7.4.1708 directory on mirror.centos.org will be emptied some time after 7.5 is released.
For reference and inspiration, here are some directories from mirror.centos.org, including both up-to-date content and potentially EOL content. SIG chairs should review the list to make sure these directories can be copied over to 7.5.18xx when that time comes. Making the decisions now would save a bit of time at 7.5 release time.
