I have an update.raucb file that contains an update for an embedded device. The file is a so called rauc bundle.
How can I view the content of a .raucb file, like manifest.raucm and root file system?
To extract the content of a rauc bundle to squashfs-root, do:
unsquashfs update.raucb
This will create a folder squashfs-root that contains a manifest.raucm file and the root file system. Depending on bundle's content, it's sometimes necessary to mount the rootfs.
