Ability to config max journal size for logs

[dtkujawski]

Describe the feature

In 2023 the HAOS was changed to force a maximum log size of 500M (GitHub Link)

Since the /etc/systemd filesystem is readonly, there is no way to edit this file. If we make a temporary binding/overlay of this file, it will not survive a HAOS reboot.

It would be nice to be able to override this value through an overlay file, like what is done for /mnt/overlay/etc/systemd/timesyncd.conf. So, if we could have this file editable in "/mnt/overlay/etc/systemd/journald.conf" that would be great.

Use cases

When running HAOS on a more beefy machine, this limit is very small and I would like to have 5GB of journal logs.

Current workarounds

There are no known workarounds to me. I can temporarily overlay my own file though "mount --bind" but it won't survive a reboot of HAOS.

Only way I know how to do this for real, is not using HAOS and using a linux installation as the OS system.

Anything else?
