Factory Reset

In this context, Factory reset means restoring a device to the original state. This is a feature of LmP, rather than of FoundriesFactory®. A reset is performed as a script in ramdisk during boot. It is triggered by the presence of specific files. Presence of the files is specified in the following order:

/var/.factory_reset
/var/.factory_reset_keep_sota
/var/.factory_reset_keep_sota_docker

Each file has specific meaning. When a higher priority file is detected, remaining files are ignored.

Full Factory Reset

When the file /var/.factory_reset is present, the script performs a full reset. A full reset means restoring contents of /etc/ and /var/ from ostree. All contents created in these directories at runtime will be erased.

Partial Factory Reset

There are currently two options in partial reset. The main difference with full reset is that the device remains connected to your Factory.

Keep SOTA

When the file /var/.factory_reset_keep_sota is present, contents of /etc/ are restored from ostree. Contents of /var/ are partially removed. /var/sota/ contents are kept to allow aktualizr-lite to be preserved. Docker images and compose apps are deleted.

Keep SOTA and Docker

When the file /var/.factory_reset_keep_sota_docker is present, contents of /etc/ are restored from ostree. Contents of /var/ are partially removed. /var/sota/ contents are kept to allow aktualizr-lite and compose-apps to be preserved. /var/lib/ is preserved as the Docker objects are stored there.

RPMB

Currently, RPMB is not cleared in either reset procedures.
