On my odroid hc2 with armbian/bullseye I found some of the logs (both in /var/log and /var/log.hdd) empty, while they should have some contens (i.e. afpd.log, kern.log, user.log, ...).   The empty files all have the timestamp of a run of armbian-ramlog at a recent reboot. In armbian-ramlog.log I found this for the run that created the empty files:   rsync: [receiver] write failed on "/var/log/journal/0d4b1c13b9a14b6d9c746402b7d7ef6f/user-1000@0005d37f46f9961b-23c015a66b68d086.j
