Change root/auterion user password

By default the password for root and auterion user is auterion. You can change it by ssh-ing into your device and run the following command passwd. Your new password will be persisted across reboots and updates. Keep in mind that your password can be overwritten by an update if the artifact has been repackaged with the password option.

Root filesystem mount option

By default the root filesystem is mounted as ReadOnly for security reasons. You can re-mount it as ReadWrite with the following command but note that if you power cycle or reboot your device, the root filesystem will be automatically remounted as ReadOnly.
# Mount Root FS as ReadWrite
mountrw
# Mount Root FS as ReadOnly
mountro
In case you want to persist your choice, you can use the following command:
# Mount Root FS as ReadWrite
ao-root-rw.sh
# Mount Root FS as ReadOnly
ao-root-ro.sh
The mount option will be reset after an update.
