      When configuring grub.cfg for a BTRFS root (in this instance, located at ROOT/funtoo), boot-update does not add the appropriate rootflags. /boot is not a separate partition or subvolume, but is located at ROOT/funtoo/boot.

      What is created by boot-update:

      menuentry "Funtoo Linux genkernel - kernel-genkernel-x86_64-3.19.0-gentoo" {
  insmod part_msdos
  insmod btrfs
  set root=(hostdisk//dev/sda,msdos1)
  search --no-floppy --fs-uuid --set 79c768ad-5512-4d14-b342-d82e49171412
  linux /boot/kernel-genkernel-x86_64-3.19.0-gentoo real_root=/dev/sda1
  initrd /boot/initramfs-genkernel-x86_64-3.19.0-gentoo
  set gfxpayload=keep
}

      In order to boot the system, the following changes must be made:

        linux /ROOT/funtoo/boot/kernel-genkernel-x86_64-3.19.0-gentoo real_root=/dev/sda1 real_rootflags=subvol=ROOT/funtoo
  initrd /ROOT/funtoo/boot/initramfs-genkernel-x86_64-3.19.0-gentoo
