DESCRIPTION

RAUC is a lightweight update client that runs on an Embedded Linux device and reliably controls the procedure of updating the device with a new firmware.

RAUC is also the tool on the host system that is used to create, inspect and modify update artifacts for the device.

This manual page documents briefly the rauc command line utility.

It was written for the Debian GNU/Linux distribution to satisfy the packaging requirements. Thus it should only serve as a summary, reading the comprehensive online manual (https://rauc.readthedocs.io/) is recommended.

OPTIONS

The following general options can be used with most commands, however not all combinations make sense.

use the given config file instead of the one at the compiled-in default path

use given certificate file or the certificate referenced by the given PKCS#11 URL

use given private key file or the key referenced by the given PKCS#11 URL

use specific keyring file

intermediate CA file name

mount prefix

overrides auto-detection of booted slot

pass extra handler arguments

enable debug output

display version

print usage

COMMANDS

bundle INPUTDIR BUNDLE

resign INBUNDLE OUTBUNDLE

Resign an already signed bundle.

Options:

status [SLOTNAME | mark-{good,bad,active} [booted|other|SLOTNAME]]

Without further subcommand, it simply shows the system status or status of a specific slot.

The subcommands mark-good and mark-bad can be used to set the state of a slot explicitly. These subcommands usually operate on the currently booted slot if not specified per additional parameter.

The subcommand mark-active allows one to manually switch to a different slot. Here too, the desired slot can be given per parameter, otherwise the currently booted one is used.

Options:

show more status details

select output format

write-slot SLOTNAME IMAGEFILE

Write image to slot and bypass all update logic.

ENVIRONMENT

Library filename for PKCS#11 module (signing only)

PIN to use for accessing PKCS#11 keys (signing only)

FILES

/etc/rauc/system.conf

The system configuration file is the central configuration in RAUC that abstracts the loosely coupled storage setup, partitioning and boot strategy of your board to a coherent redundancy setup world view for RAUC.

RAUC expects its central configuration file /etc/rauc/system.conf to describe the system it runs on in a way that all relevant information for performing updates and making decisions are given.

Similar to other configuration files used by RAUC, the system configuration uses a key-value syntax (similar to those known from .ini files).

AUTHORS

rauc is developed by Jan Luebbe, Enrico Joerns, Juergen Borleis and contributors.

This manual page was written by Michael Heimpold <mhei@heimpold.de>, for the Debian GNU/Linux system (but may be used by others).
