I found the talk really interesting, especially how CentOS-Stream means SIGs can fork the hell out of it.
The Hyperscale SIG highly modifies it, by backporting tons of packages, shipping modern Kernel, systemd and more.
They also ship btrfs-kmod to use BTRFS like an out-of-tree driver on regular RHEL/CentOS.
They enable livepatching for the Kernel.
And a lot more!
PS: if you are looking for the official LTS Linux kernel, built for Fedora, CentOS & RHEL, check out this COPR
Here’s something to get you started.
Don’t take my word for it, tho. Do your own research as well!
