How do I configure journald so that it never, ever, ever deletes my logs.
Yes, what I want to do is tell journald to keep writing until the disk (read: /var partition's filesystem) is full.
No, I don't want it to keep storing to memory until the RAM is full.
According to man 5 journald.conf,
SystemMaxUse=, SystemKeepFree=, SystemMaxFileSize=, SystemMaxFiles=,
RuntimeMaxUse=, RuntimeKeepFree=, RuntimeMaxFileSize=, RuntimeMaxFiles=
Enforce size limits on the journal files stored. The options
prefixed with "System" apply to the journal files when stored on a
persistent file system
...
The first pair defaults to 10% and the second to 15% of the size of
the respective file system, but each value is capped to 4G.
So the default is some percent of the filesystem with a cap at 4G. Unfortunately, I don't see any mention of how to set it to unlimited in the above man page.
How do I make journald never delete my logs? Bonus points for additional options that increase rotation & compression, etc.
