Well... That would be one way to solve this.  Default to --writable-root
if UID is zero.

I was thinking about programs that are expected to be run as a root and
have hard-coded PID file, lock file or something else under /run.  But I
have no example to put forward.  So maybe your version is enough, and we
can revisit this in another pass later if the need realizes?

I do not really have a strong opinion either way here, just wanted to
raise the point for consideration.  Feel free to proceed with the
original version. ^_^
