Details:
update-grub creates an invalid grub.cfg due to grub-probe reporting multiple
devices:
|mcelrath@tardis:~> grub-probe --target=device /
/dev/nvme4n1p1
/dev/nvme3n1p1
/dev/nvme2n1p1
/dev/nvme5n1p1
grub-mkconfig puts this on the kernel's command line, which breaks the command
line due to the newlines in the output.
The fix is easy, just use sort and head to grab the first device. (BTRFS
doesn't care which device is used as the target of the mount, it can find the
other required physical devices)
(patch attached)
