Given there is consensus that legacy BIOS is on its way outI don't think this statement is true, unless Fedora doesn't want to be
considered for a bunch of popular VM hosts (e.g. Linode and such) that
have no stated plans to support UEFI.
Maybe "legacy BIOS on physical hardware" is on its way out
It's not an maybe, it is on it's way out either physically or simply via firmware update [1]
"In the bios, upgraded to 810 the option to enable legacy boot is greyed out"
So how do people propose the situation to be handled when firmware from vendors, disables the legacy boot option via firmware update.
Is Fedora supposed to block/blacklist those firmware updates via some plugin in lvfs based on user feedback when their legacy boot mode suddenly stops working or is it expected that upstream lvfs team looks into this or what?
Fedora doesn't install these updates. Users install these updates, when they have a problem
In the past they did, today users ( including the novice ones ) update it as Gnome notifies them about available update just like they do when they receive anyother software update notification.
Really? I didn't know that. At least on my computers, Gnome has never notified me about a BIOS update from my motherboard vendor. Besides, it's proprietary software, so I wouldn't expect Fedora to be offering it by default. Doesn't it need adding an extra software repository?
It's fwup/lvfs [1] and nope you dont need to jump through any
additional hoops for that, it just work ( or it does not if the
vendor is not part of lfvs ).
And besides, non-UEFI systems don't normally receive BIOS updates that break legacy boot, because legacy boot is the only boot option available, so what is your point, exactly?
Obviously this was for dual bios mode ( legacy and uefi ) ( otherwise the option to disable it would not be there ) in which the vendor himself seemingly decided to disable the legacy part of the bios via firmware update which highlight the fact that we somehow need to deal with that situation if we want to continue to support the legacy bios option.
How I have no clue, which is why I pointed at an potential lvfs plugin or the lvfs team.
I think we should check the BIOS date in the installer and deprecate (as in, print warnings to the user in the installer) legacy boot on newer systems (e.g. newer than 2017 or some other cutoff date, when we decide that UEFI becomes more stable), an by deprecate, I mean, show warnings to the user and suggest that they continue on their own risk. Of course, we should also check for virtual machines, like e.g. QEMU/SeaBIOS, that are known to be stable in legacy BIOS mode and not show the warning in them, even if the BIOS date is new (although SeaBIOS seems to use an old date - 06/23/99).
That's something that needs to be worked out with the Anaconda team but I think Javier already provide the best path forward with regards to Anaconda when I started the dialog two years ago but for whatever reason that's not part of Robbie's proposal.
