lock

My /run/lock/ directory is empty except for ./whoopsie/. I have understood /run/lock/ as a replacement for /var/lock/ but was surprised to find it entirely empty.

Is whoopsie meant as a deterrent from using this directory?

I did find other lock files under /run/, though. Most notably in /run/user/<me>/. I would have expect per-users lock files in /run/lock/user/ and not in a separate directory.

Hoping for some clarification!
