Bug#602333: /usr/bin/fusermount: fusermount allows unmount any filesystem

I've been trying to get to the bottom of this bug over the past day, not helped by libfuse redirecting fusermount's stderr to /dev/null. There are actually two bugs here with roughly the same effect. When mounting, fusermount must: 1. Make the mount() system call; 2. Run the mount command to
