This isn't reliably done through either firmware or bootloader file system drivers for reasons I state in the immediately previous email. But also the GRUB folks aren't ever going to write to any file system with their drivers, no matter what that file system is. It's against their philosophy. What is on the table is something standardized across bootloaders, akin to the GRUB grubenv file. It could be used for saving state where it's not possible, reliable or desired to write to NVRAM. -- Chris Murphy _______________________________________________ devel mailing list -- devel@lists.fedoraproject.org To unsubscribe send an email to devel-le...@lists.fedoraproject.org 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@lists.fedoraproject.org/message/BB2TWG3SDCPF5CIOY2NTBCA655KQI7DE/
