Some of this is argued in the two BootLoaderSpecs. Mainly to avoid stomping on each other's installations and bootloaders, and a bit less redundancy instead of every distro having its own $BOOT. But really, how many people multiboot 2 or more Linux distros? My shits n giggles guess? Most common is Windows + Linux. Next most common macOS + Linux. Next most common Linux only. I think in some sense we're in the weeds on multibooting. It is possible we're overvaluing shared $BOOT. > I'd like to point out that $BOOT doesn't have to be shared to dual-boot > multiple distros or benefit from other details of BLS. True. Although the original BootLoaderSpec script file format only supports paths relative to $BOOT. There's no way to reference other volumes, even if they are readable by the firmware. You'd have to depend on the bootloader's native configuration file format instead of BLS format for such a feature, meaning no way to support it with one format across bootloaders. > Each installed OS that wants to use some derivative of BLS really *can* > just each have their own $BOOT and even use different bootloaders to > implement BLS.

The change is a win, even if it's not a warm and fuzzy embrace of the whole BootLoaderSpec. It leaves the door open to either distros constraining their implementations toward BootLoaderSpec, or the broadening of the BootLoaderSpec to grow the market. My personal assessment is that the latter is more likely. -- Chris Murphy _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://getfedora.org/code-of-conduct.html List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@xxxxxxxxxxxxxxxxxxxxxxx/message/7WXRGNDMQ7VN73QUQN6TVRCW53VS73YJ/
