1. There is no need to specify rw argument -- bind mounts are read-write by default. 2. There is no point in parsing /proc/self/mountinfo after performing a mount, especially if we don't check whether the fs is mounted or not -- the only outcome from it could be an error from our mountinfo parser, which makes no sense in this context.
