And this makes sense in the common X86-ish desktop world. "PC"s are never
normally "headless" and most "PC" uses don't need sshd and it would be a
possible security hole, if setup wrong... OTOH, the little ARM SBCs (RPis,
Beagles, etc.) are almost always "headless", so having sshd there is often
essential.
