OK, up and at it. A little bit of scripting gets me the first line of the journal for each available boot: What I notice is that the rebooting happened every few hours during the day, when I was trying to keep that Python code going, and not at all after 9PM when I stopped doing so.
I had tried printing the last line too with "END {print}" but that didn't seem informative.
Code:
pi@pi0w7:~/bin $ for i in `seq -6 1 0`; do journalctl -b $i --no-pager | awk 'NR==1 {print} END {}'; doneNo journal boot entry found for the specified boot (-6).No journal boot entry found for the specified boot (-5).No journal boot entry found for the specified boot (-4).Dec 19 11:52:39 pi0w7 kernel: Booting Linux on physical CPU 0x0Dec 19 14:58:19 pi0w7 kernel: Booting Linux on physical CPU 0x0Dec 19 16:25:31 pi0w7 kernel: Booting Linux on physical CPU 0x0Dec 19 20:22:29 pi0w7 kernel: Booting Linux on physical CPU 0x0I had tried printing the last line too with "END {print}" but that didn't seem informative.
