Public bug reported:
On a new install of wily. update-grub is improperly inserting a
carriage return on the "linux" line of the grub.cfg menu items, between
the two devices of a btrfs raid1 system (which for my system is in a
luks container). The menu entries all looks like this:
menuentry 'Ubuntu' --class ubuntu --class gnu-linux --class gnu --class os
$menuentry_id_option
'gnulinux-simple-/dev/mapper/luks.root1_/dev/mapper/luks.root2' {
recordfail
load_video
gfxmode $linux_gfx_mode
insmod gzio
if [ x$grub_platform = xxen ]; then insmod xzio; insmod lzopio; fi
insmod part_msdos
insmod btrfs
set root='hd2,msdos1'
if [ x$feature_platform_search_hint = xy ]; then
search --no-floppy --fs-uuid --set=root --hint-bios=hd2,msdos1
--hint-efi=hd2,msdos1 --hint-baremetal=ahci2,msdos1
fe74974e-3e23-43af-bfb1-7b520673c52b
else
search --no-floppy --fs-uuid --set=root <UUID>
fi
linux /@s3970boot/vmlinuz-4.2.0-23-generic root=/dev/mapper/luks.root1
/dev/mapper/luks.root2 ro rootflags=subvol=@ quiet splash $vt_handoff
initrd /@s3970boot/initrd.img-4.2.0-23-generic
}
Removing that <cr> makes everything boot fine.
