The Linux Vendor Firmware Service is a secure portal that allows hardware vendors to upload firmware updates, see https://lvfs.org
This is where hardware makers can publish firmware for off-shelve peripherals to be consumed via fwupd.
Sometimes, edge systems are disconnected from public networks, in this case embedding firmware updates into the images will help customers update their peripherals (modems, cameras, etc..).
The osbuild pipeline code could look like:
{
"type": "org.osbuild.fwupd.firmware",
"inputs": {
"images": {
"type": "org.osbuild.lvfs",
"origin": "org.osbuild.source",
"references": {
"com.synaptics.prometheus.0xDF.firmware": {
"version": "10.01.3273255"
}
}
},
"options": {
"destination": {
"type": "vendor-firmware",
"path": "/usr/share/fwupd/remotes.d/vendor/firmware",
}
},
The LVFS CDN contents can be found here https://cdn.fwupd.org/downloads/firmware.xml.xz
And this is a snippet example for the above reference:

The above json for osbuild would result in installing the https://fwupd.org/downloads/39f476f9903f28d0d851af5b42883d5bf0eb0809c16a53ec05a1575efb698f5f-Synaptics-Prometheus-10.01.3273255-0xDF.cab file under /usr/share/fwupd/remotes.d/vendor/firmware
