I'm going to go out on a limb here and say its an O_DIRECT error. Reason
I'm guessing this is that O_DIRECT is not supported on tmpfs and when you
attempt to open() a file with O_DIRECT and its not supported you'll get
back -EINVAL from the kernel. Newer systems have /run as tmpfs and /var/run
symlinked to /run.
