@garrett @trelane Debian + Suse have signed sd-boot in place, and in particular Suse is defaulting to it in some editions. Arch is pretty much there too. The problem is pretty much Fedora/RH at this point. RH's boot team has been pursuing alternatives to both grub and sd-boot for the last decade or so, with – let's say – "mixed" results, and always sinking more and more resources into it. At this point I figure it's pretty much down to that, since too many folks from other distros…
@trelane @pid_eins Right, agreed. That's my point. It's there. Why aren't distros using it already? (Inertia, I'm sure, but that's not a good reason.)
