Hi,

As the command need to write to disk using blocklist information,
which is not always correct (such as tail packing, sparse block), I
use a magic header for verification. The length field is used to
indicate the length of the block. because the command can't expand
file, otherwise it would need to update fs information, which is too
much for grub.

I have no objection for the rename, although there should be two env
commands, one to load and one to save.
