If I wait long enough systemd give up and drops to maintenance mode. Looking in the journal I see events like this: Sep 19 08:24:22 ubuntu-xps13 systemd[1]: dev-disk-by\x2duuid- 63cd6483\x2ddf95\x2d4426\x2d916e\x2d8c28becbfd8f.device: Job dev-disk- by\x2duuid- 63cd6483\x2ddf95\x2d4426\x2d916e\x2d8c28becbfd8f.device/start timed out. Searching on the internet indicates that this happen if devices reported by udev don't have the "systemd" tag, and I find that they do not have the tag when the boot times out but they do have the tag when boot does not time out. This happens once for every 3 or 4 boots and with both 4.4 and 4.8 kernels. I'm attaching the output of 'journalctl -xb' and 'udevadm info --export-db' from a timed-out boot.
