Yes, pretty much.

(Well, I mean, there are scenarios you could think where you want to
tell journald to temporarily switch to volatile logging via "journalctl
--relinquish-var", then do something with /var/log (like replace it,
backup it, overmount it, whatever), and then eventually want to switch
back to using it, which you then can do with "journalctl --flush".
