Fedora Log Files

This document describes the guidelines for log file(s), for use and inclusion in Fedora packages.

Log Files on the filesystem

Packages with log files must reside in their own directory under /var/log which must be named /var/log/$package_name

Each log file in that directory must end with .log filename.

Each package that ships log files must also ship a logrotation file that rotates the log file(s).
