Kirk McKusick 77b63aa0fc Since the switch to GPT disk labels, fsck for UFS/FFS has been ... unable to automatically find alternate superblocks. This checkin places the information needed to find alternate superblocks to the end of the area reserved for the boot block. Filesystems created with a newfs of this vintage or later will create the recovery information. If you have a filesystem created prior to this change and wish to have a recovery block created for your filesystem, you can do so by running fsck in forground mode (i.e., do not use the -p or -y options). As it starts, fsck will ask ``SAVE DATA TO FIND ALTERNATE SUPERBLOCKS'' to which you should answer yes.
