In case a systemd service disables itself while init is still in its boot sequence the reloading of the service files can be problematic. In that case: It seems that systemd looses the state of .device units, and some services depend on such units (namely serial consoles such as serial-getty@ttymxc0.service). As a result no getty is spawned on the affected serial tty. After a power-cycle the second boot (which does not disable services) succeeds.
The following sequence shows this problem: | Jan 09 16:36:28 apalis-t30 systemctl[162]: Removed /etc/systemd/system/sysinit.target.wants/run-postinsts.service. | Jan 09 16:36:28 apalis-t30 systemd[1]: Reloading. | ... | And then the failing one: | Feb 22 15:33:15 apalis-t30 systemd[1]: dev-ttyS0.device: Job dev-ttyS0.device/start timed out. | Feb 22 15:33:15 apalis-t30 systemd[1]: Timed out waiting for device dev-ttyS0.device. | Feb 22 15:33:15 apalis-t30 systemd[1]: Dependency failed for Serial Getty on ttyS0. | Feb 22 15:33:15 apalis-t30 systemd[1]: serial-getty@ttyS0.service: Job serial-getty@ttyS0.service/start failed with result 'dependency'. | Feb 22 15:33:15 apalis-t30 systemd[1]: dev-ttyS0.device: Job dev-ttyS0.device/start failed with result 'timeout'. | Feb 22 15:33:15 apalis-t30 systemd[1]: Reached target Login Prompts. (the time has been updated between this two events, but that does not influence the issue) Using --no-reload in the service file avoids the "Reloading." message above and seems to not cause such issues anymore.
