GRUB_SAVEDEFAULT and grub-reboot with GRUB_DEFAULT=saved do not work if
grubenv file resides on an LVM partition or a RAID device, since those
cannot be written to. This patch adds a note regarding this issue into the
manual.
This is my first patch submission, so please let me know if I messed
something up. Thanks!
