Current status
- Targeted release: Fedora Linux 38
- Last updated: 2022-12-21
- FESCo issue: <will be assigned by the Wrangler>
- Tracker bug: <will be assigned by the Wrangler>
- Release notes tracker: <will be assigned by the Wrangler>
Detailed Description
Currently, the journal can occupy up to 4 GB of disk space. 4 GB is a lot of space to use for logs, and this has been a source of user complaints.
Limiting the journal logs to 3 months retention is primarily intended to reduce the amount of disk space used. The time-based limit also intended to set the journal limit based on the need for the data, as opposed to the more arbitrary disk space criteria.

Benefit to Fedora
- Reduce the amount of disk space used for logs, thus increasing the amount of space available for other things
- Reduce user complaints
- A more privacy-conscious design
