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!

Well that certainly explains why it hasn't been working for me.  Why
can't it be written to?

This fails to correctly describe either reason or the limitations of
save_env. I wrote a similar paragraph myself and committed it
