A lot of other As a cross-distro chap, I can attest to this. Specially with sendmail. Everytime I spot sendmail in a Fedora/RHEL/CentOS box I wonder when will it happen. Together with sudo-by-default (and root logins disabled & discouraged by default). Back to the topic, what happens when I boot from a LiveCD to diagnose a borked machine? Some FAQs that come to mind that google doesn't answer: - The easy part: I run journalctl -r /path/to/rootpart/ -- what if /var/lib/ is a mountpoint? Can I point directly to the 'database' file? - What guarantees of completeness/consistency can we expect in practice from the journal in a hard poweroff situation? What is the price in terms of fsync() calls? - What if the database file is corrupt? On occasion, I have read partially corrupted logfiles with less. Sure, there was a chunk of crud in the middle, but I could read past it. While the un-corrupted bits were far from reliable, they did provide helpful info. This last item is my main worry. Perhaps working on prototype XOs, trying to sort out kernel/driver issues is not a mainstream use case... cheers, m -- martin.langhoff@xxxxxxxxx - ask interesting questions - don't get distracted with shiny stuff - working code first ~ http://docs.moodle.org/en/User:Martin_Langhoff -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel
