Title:
  10_linux_zfs not adding new kernel

Status in grub2 package in Ubuntu:
  New

Bug description:
  grub does not manage to change the config so it boots from the latest
  kernel. It still uses the kernel on the original first snapshot I
  made. It finds the new kernel but does not add it to grub.conf

  I had to change the 10_linux_zfs to even add a config at all (somehow does not use the \t without it):
  echo "${boot_list}" | awk 'BEGIN{FS="\t"}{ gsub(/\\t/, "\t")} { print $0 } '
