Checked the logs, which wasn't helpful; there was no persistent log
Unsure of your setup, but this may be useful for someone:
## See the selection of previous boot logs:
journalctl --list-boots
## Check the logs from the *previous* boot:
journalctl --boot -1
## To check the *previous* boot logs for udev and postfix
## (random examples):
journalctl --boot -1 --unit udev* --unit postfix
## If booted from USB and wanting to check previous non-USB boot,
## add a --directory pointing to the HD:
journalctl --directory /mnt/myHD/var/log/journal/... --boot -1
etc.
Was very concerned about "systemd is using binary logging, this breaks
everything!" way back when, however...
Turns out, journalctl is pretty powerful and has some really great features.
