Thanks! However, this doesn't work on a brand new CoreOS install because rsync can't create folders recursively (error: rsync: mkdir "/opt/sbin" failed: No such file or directory). I simply added a ExecStartPre = -/usr/bin/mkdir -p /opt/sbin in [Service].

@shanoor, nice catch. I added your suggestion.

Why create sbin/ in /opt/ if you're just going to rm it immediately? Just create /opt instead to resolve the rsync issue.
