Hello, I'm wondering why journald stores journal files under /var/log/journal/$MACHINE_ID instead of just /var/log/journal.
I found the commit that introduces this change, but it contains no justification: https://github.com/systemd/systemd/commit/ed49ef3f349bcd4f0483ba8254a2537fe8e9cd17 I also searched the systemd-devel mailing list archive, but didn't find anything. I know that journal namespaces are a thing, but the namespaces share the same machine id, so I don't think they are the reason for it. I also think that journal namespaces came quite some time after the commit mentioned above. Does anyone have some insights they are willing to share? Thanks, Jakub
