BugLink: https://bugs.launchpad.net/2039144 The X13s comes up with a random wifi MAC address, because it's hidden probably in secret storage that the kernel can't get to (yet). This can be problematic for some environments and MAC address randomization should really be handled by NetworkManager. So set a unique and persistent MAC based on /etc/machine-id.
