Very true for mainstream distros, but there’s more: Linux updates in the background. No matter how long it takes(if you for example use Gentoo), there is zero downtime. And with kexec your system can be its own bootloader and can do insane stuff like starting new kernel without re-running POST, which is on servers is very important(because they have shitty BIOS that takes ages to boot).
