Gonéri Le Bouder 042aa9ab5a use wipefs to erase FS meta information ... destroy_disk_metadata should destroy a bit more data than expected if we want to be sure grub won't conflict with remaining bits of filesystem. grub probes the hard drive to find remaining partition or filesystem. If it find something, it will refuse to install itself on the disk. By using wipefs instead of dd, we not only erase the MBR and partition table but also all trace of filesystem, raid or partition-table signatures (magic strings). This without extra Python code. wipefs is part of util-linux which is available on all the Linux distribution.
