Nice catch! Indeed, hexdump has special handling for the whole partitions. And it actually tries to satisfy the low level API by converting offset to the sector number and skipping the remainder. I guess it could be simplified if grub_disk_read() is used. > BTW, I also find an ingesting situation when writing the load_env > command.

In that case it may be justified. -- Regards, Pavel Roskin _______________________________________________ Grub-devel mailing list Grub-devel@gnu.org http://lists.gnu.org/mailman/listinfo/grub-devel
