To help me understand the problem, exactly what logging was persistent
previously, and isn't persistent now? Can you please give us an example?
Robie,
As I understand, Upstart's logging about boot and managed services was persistent by default. From http://upstart.ubuntu.com/cookbook/ I find this:
"For a standard Ubuntu Maverick (10.10) system, the output will be sent to file /var/log/daemon.log, whilst on newer Ubuntu systems such as Ubuntu Natty (11.04), the output will be directed to file /var/log/syslog."
In turn, I understand that "syslog" logging has been persistent-by-default per years.
It seems that with the switch to systemd as the init system, the logging that originates from the init system became not-persistent by default.
The linked issue had examples of users who expected to find details about service logging or boot logging from a previous boot which was not found, when it would have existed under Upstart.
