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.

--cert=PEMFILE|PKCS11-URL

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

--key=PEMFILE|PKCS11-URL

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

--keyring=PEMFILE

use specific keyring file

--intermediate=PEMFILE

intermediate CA file name

--mount=PATH

mount prefix (/mnt/rauc by default)

--override-boot-slot=BOOTNAME

overrides auto-detection of booted slot

--handler-args=ARGS

pass extra handler arguments

-d, --debug

enable debug output

--version

COMMANDS

bundle INPUTDIR BUNDLE

Create a bundle from a content directory.

Options:

--signing-keyring=PEMFILE

--mksquashfs-args=ARGS

mksquashfs extra args

resign INBUNDLE OUTBUNDLE

Resign an already signed bundle.

Options:

--no-verify

disable bundle verification

--no-check-time

don’t check validity period of certificates against current time

--signing-keyring=PEMFILE

verification keyring file

extract BUNDLE OUTPUTDIR

Extract the bundle content to a directory.

Options:

--trust-environment

trust environment and skip bundle access checks

extract-signature BUNDLE OUTPUTSIG

Extract the bundle signature.

Options:

--trust-environment

trust environment and skip bundle access checks

convert INBUNDLE OUTBUNDLE

Convert an existing bundle to casync index bundle and store.

Options:

--trust-environment

trust environment and skip bundle access checks

--no-verify

disable bundle verification

--signing-keyring=PEMFILE

verification keyring file

--mksquashfs-args=ARGS

mksquashfs extra args

--casync-args=ARGS

casync extra args

encrypt INBUNDLE OUTBUNDLE

Encrypt a crypt bundle.

Options:

--to PEMFILE

recipient cert(s)

install BUNDLE

Install a bundle.

Options:

--ignore-compatible

disable compatible check

--progress

show progress bar

info BUNDLE

Print bundle info.

Options:

--no-verify

disable bundle verification

--no-check-time

don’t check validity period of certificates against current time

--output-format=[readable|shell|json|json-pretty]

select output format

--dump-cert

dump certificate

--dump-recipients

dump recipients

mount BUNDLE

Mount a bundle for development purposes to the bundle directory in RAUC’s mount prefix. It must be unmounted manually by the user.

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:

--detailed

show more status details

--output-format=[readable|shell|json|json-pretty]

select output format

write-slot SLOTNAME IMAGEFILE

Write image to slot and bypass all update logic.

ENVIRONMENT

RAUC_KEY_PASSPHRASE

Passphrase to use for accessing key files (signing only)

RAUC_PKCS11_MODULE

Library filename for PKCS#11 module (signing only)

RAUC_PKCS11_PIN

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.
