Public bug reported: Right now, /etc/grub.d/10_linux insists on
GRUB_CMDLINE_LINUX="rootflags=subvol=${rootsubvol} ${GRUB_CMDLINE_LINUX}" and the only way for me to tell a remote box that booting with a degraded RAID1 for a btrfs root filesystem is via $ grep degraded /etc/default/grub GRUB_CMDLINE_LINUX="rootflags=subvol=@,degraded" but this is brittle because it doesn't do the ${rootsubvol} logic from /etc/grub.d. Please provide a better way.
