+# Enable forwarding of journald logs to the syslog service
+# This helps to ensure compatibility with legacy log systems
+# that rely on syslog for centralized log collection.

+ForwardToSyslog=yes
+#
+# Enable compression for journald logs to save disk space.
+# Older log files will be compressed automatically, helping to
+# retain logs longer without using excessive storage.

+Compress=yes

 # Configure journald to persistently keep logs, so that we can inspect
 # them after a reboot has already occurred. This helps debugging, and
 # also can make the collection of support bundles more useful.
