This did not cause real problem but is good for reproducible builds. I hit it with recent bootinfoscript that displays embedded config; I was puzzled by random garbage at the end. Prezero memory buffer used to assemble core.img. This makes individual memset redundant. Also ensure buffer is filled with zeroes in several other places. Also remove redundant zeroing code where we fill in the whole memory block anyway.
This is GRUB 2, the second version of the GRand Unified Bootloader. GRUB 2 is rewritten from scratch to make GNU GRUB cleaner, safer, more robust, more powerful, and more portable. See the file NEWS for a description of recent changes to GRUB 2. See the file INSTALL for instructions on how to build and install the GRUB 2 data and program files. Please visit the official web page of GRUB 2, for more information. The URL is <http://www.gnu.org/software/grub/grub.html>. More extensive documentation is available in the Info manual, accessible using 'info grub' after building and installing GRUB 2. There are a number of important user-visible differences from the first version of GRUB, now known as GRUB Legacy. For a summary, please see: info grub Introduction 'Changes from GRUB Legacy'
