Comment 7 for bug 1817627

This is a scary bug. I was just trying to verify the syntax of a timer file using systemd v237. I got an error message back suggesting something like rm -rf / was attempted to be executed instead!

   $ sudo systemd-analyze verify /etc/systemd/system/my.timer
   Attempted to remove disk file system, and we can't allow that.

Backporting this fix could help reduce the risk of heart attacks.
