Hi, Jens. The firmware DVD has been discussed quite a bit over the years, sometimes with rather interesting suggestions and/or controversy [1,2,3,4,5]. I'm touting my own horn a bit here, but I've been working with these challenges for years, and I'm still passionate about finding good solutions. I understand that the mechanisms around DUPs will not be changed any time soon (although there's the fwupd thing [2]) – and its dependency on proprietary libraries (srvadmin family) for determining component IDs and similar, being rather tailored for RHEL-style systems – so a live environment for firmware updates is probably the best kind of solution given the situation. I keep hoping that this live env will be designed for the heterogenous 10'000- node case, where the firmware upgrade procedure is not only automatic, but well thought-out in such a way as to reduce the deployment cost (resource-wise) and to provide as much insight as possible, reducing blind faith. Some quick examples: Make things network bootable, always. The initial image should be tiny; fetch bulk data on-demand from a repo, which must be possible to mirror locally to remove upstream dependencies. Separate the component inventory collection (boot up, collect inventory, report it plus a "waiting for action" state) from the update procedure (triggered in bulk via simple APIs, push or pull) – with the option of combining the two for zero interaction. Add detailed instrumentation to facilitate reporting of progress, error, completion, etc. See also [1,2].
