💫 DESCRIPTION 💫

So the configured string gets printed right after utsname during task dumps. That's the whole vibe. It's usually used to add arch-specific system identifiers. If an arch wants to make use of such an ID string, it should initialize this as soon as possible during boot. Don't sleep on it 👑
