FWupd.org is a Linux firmware update service, roughly like Windows Update, but for Linux.
It is nice to have a central place for firmware updates, so you don’t have to rely on the tools from a single OEM. Right now, most OEMs force you to use their firmware upedate tools. Windows OEMs mostly don’t bother to use Windows Update. And it looks like that problem is not OS-centric: Linux OEMs mostly don’t bother to use fwupd. However, many Linux vendors are not helping customers with firmware updates, look at second half of this page for all the vendors that suck:
It looks like Purism is heading toward supporting fwupd:
I am suprised that System76 is going their own route and not supporting fwupd, they claimed they were going to support it, but they’ve gone their own direction, sad.
Before you buy a system from a Linux OEM, ask them if they support fwupd for firmware updates. If they do not, ask them when they are going to support it.
