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.
