On my Pioneer with HDD, in plinth, in the general configuration, I have enabled writing the journal to the disk.
It is the second time in a few days that my freedombox becomes unreachable, not even by ping so I removed the power and put it back. When I check the journal with sudo journalctl, what there is before the last boot is something really old, not what happened before so I have no clue at all what happens when I loose control.
Is there something else to ensure that the journal is written to the disk?
