I don't keep a digital journal so to speak but when I would do something ad-hoc/break-fix in the workplace I would always add a comment to syslog on-the-fly in case someone asks why I did a thing. So I suppose this is sort of a digital journal. Syslog has data retention requirements in this case and was also replicated to Splunk. echo "Fixing ssh key permissions for ansible. --my.name JIRA-1000101" | logger Logger sends the text to syslog. If someone detected a system change they will eventually also see my message and can review the JIRA that hopefully answers any questions they might have as well as showing my work and approval process. That has saved me from many emails and meetings and saved me a lot of time. One could run a syslog server on their home/vpn-mesh and/or use rsyslog with TLS and send messages from any terminal to the syslog server. I have also found this to be a useful way to distribute commands and log feedback for home automation. Not command injection but automation that looks for keywords and takes actions.
