Pressing the “reset” button on a device loads the default configuration script and creates a backup of the previous configuration. This may contain sensible information (passwords, ip addresses, queue configurations, and so on…).
It would be handy to have an option to disable the automatic backup, like skip-backup=yes in the /system reset-configuration. It may be something like /system routerboard settings set automatic-configuration-backup=disabled.
This would make it simple to regain access to a troubled devices compared to the protected routerboot, and at the same time prevents to expose configuration details to malicious users.
