(for an Arch Linux system) Is it possible to change the storage location of the system journal to a specific directory?
How can I change the save location of the system journal?
arch linux;journald
Assuming you mean the location that journald writes to, I think not. The configuration file for journald is /etc/systemd/journald.conf, and the documentation for it doesn't list a way to choose locations. You might be able to work around it by making /var/log/journal a link to somewhere else, or mount something on that directory.
