root password is reset after update

I've set the access level to "Superuser" and entered my root SSH password via the menu entry "Set root password".

However, I've noticed that after each VenusOS update I cannot login as root anymore:

Permission denied, please try again.

Is the root password overwritten during the update?

Hi @XZv

Don't know if it's a bug or it's intentional, but unfortunately, yes, the password is overwritten during update...

Is there a known backup strategy that survives the update?

Hi @XZv

I, for one, am entering it again.

But Linux stores the password in the /etc/shadow file.

In VenusOS, the sole folder that survives the upgrade is /data folder.

Don't know if it will work, but you may copy the shadow file to /data folder and then, after upgrade, copy it back to /etc folder. Maybe make a script that will automate it.
