Vendor Firmware
===============

These are the steps to add vendor that is installed as part of an OSTree image:

* Change `/etc/fwupd/remotes.d/vendor.conf` to have `Enabled=true`
* Change `/etc/fwupd/remotes.d/vendor.conf` to have the correct `Title`
* Deploy the firmware to `/usr/share/fwupd/remotes.d/vendor/firmware`
* Deploy the metadata to `/usr/share/fwupd/remotes.d/vendor/vendor.xml`

The metadata should be of the form:

<?xml version="1.0" encoding="UTF-8"?>
    <components version="0.9">
      <component type="firmware">
        <id>FIXME.firmware</id>
        <name>FIXME</name>
        <summary>FIXME</summary>
        <developer_name>FIXME</developer_name>
        <project_license>FIXME</project_license>
        <description><p>FIXME</p></description>
        <url type="homepage">http://FIXME</url>
        <releases>
          <release version="FIXME" date="2017-07-27" urgency="high">
            <size type="installed">86406</size>
            <location>firmware/FIXME.cab</location>
            <checksum filename="FIXME.hex" target="content" type="sha1">96a92915c9ebaf3dd232cfc7dcc41c1c6f942877</checksum>
            <description><p>FIXME.</p></description>
          </release>
        </releases>
        <provides>
          <firmware type="flashed">FIXME</firmware>
        </provides>
      </component>
    </components>

Ideally, the metadata and firmware should be signed by either GPG or a PKCS7
certificate. If this is the case also change `Keyring=gpg` or `Keyring=pkcs7`
in `/etc/fwupd/remotes.d/vendor.conf` and ensure the correct public key or
signing certificate is installed in the `/etc/pki/fwupd` location.

Mirroring a Repository
======================

The LVFS currently outputs XML with absolute URI locations, e.g.
`<location>http://foo/bar.cab</location>` rather than `<location>bar.cab</location>`

This makes mirroring the master LVFS (or other slave instance) somewhat tricky.
To work around this issue client remotes can specify `FirmwareBaseURI` to
replace the URI of the firmware before it is downloaded.

For mirroring the LVFS content to a new CDN, you could use:

[fwupd Remote]
    Enabled=true
    Type=download
    Keyring=gpg
    MetadataURI=https://my.new.cdn/mirror/firmware.xml.gz
    FirmwareBaseURI=https://my.new.cdn/mirror

New instances of the LVFS can actually output a relative URL for firmware files,
e.g. `<location>bar.cab</location>` and when downloading the `MetadataURI` name
and path prefix is used in this case.
This is not enabled for the "upstream" LVFS instance as versions of fwupd older
than 1.0.3 are unable to automatically use the `MetadataURI` value for firmware
downloads.
