Thanks to the big work of the upstream QA team, a minor version upgrade in CentOS is smooth and painless. A CentOS machine fetches the security updates from an URL like
http://mirror.centos.org/centos/$releasever/updates/$basearch/Where $releasever is currently 6, and $basearch is x86_64.
This is different in NethServer, because our YUM repositories are always accessed with the minor version number. For instance, we use 6.7 instead of 6. This difference causes troubles with IPv6 and YUM, and has been signaled various times in other threads; for instance 1246, 2171, 2256.
I propose a change of the upgrade policy: let's adopt the same policy of upstream and point to the major number (6) repository. When CentOS 6.8 is released NethServer behaves exactly like CentOS; thus it continues to receive security updates, that is very important for me.
What do you think?
