Yes i also didn’t called cent os steam as a lts but as he said he want a stable distro like fedora 34 so as cent os steam 9 build on f34 and it is stable but not upto the lts level but far newer packages as far my knowledge goes so it is a good balence else fedora 34 is also a good option as it has its life it is supported for 13 months…
And i was wrong centos steam is closer to redhat but for a general user it is same as fedora.
