I'm a bit confused, why was this not a problem on whinlatter and scarthgap then?
Both of them have either centosstream-8 or centosstream-9 as their lsb string in
poky.conf.

https://git.yoctoproject.org/meta-yocto/tree/meta-poky/conf/distro/poky.conf?h=whinlatter
https://git.yoctoproject.org/meta-yocto/tree/meta-poky/conf/distro/poky.conf?h=scarthgap

Even CentOS Stream 8 images report centos-8 (with a local docker image):

$ docker run --rm -it quay.io/centos/centos:stream8 bash
[root@c33732bb804a /]# cat /etc/os-release
NAME="CentOS Stream"
VERSION="8"
ID="centos"
ID_LIKE="rhel fedora"
VERSION_ID="8"

Should we backport your change to both of these branches?

Antonin
