[systemd-devel] journal: question regarding retention options by priority/identifier/unit

[SCOTT FIELDS]

In the syslogd configuration, you can arrange to have specific retention factors for a given class of information.

AKA, I can have all kernel messages go to a specific file and that file can have a retention/rotation specified by size or date

For example, I can ensure I have 90 days of data for 'authpriv' level syslog data, if audit requires it. And that data would ONLY include 'authpriv' level data.

I don't see any options in journald to limit the scope for 'system' journal data, when configured to be persistent.

Are there any configuration options (or options in plan for the future) that will allow me to split this level of data into different managed storage with its own retention polices, much like how syslogd currently allows?

The long term goal in this case is to deprecate syslogd for audit record retention (among other uses).
