This is easier said as done. mke2fs doesn't touch the devices boot sector.
This is required as mke2fs's job is not to think about booting. Actually
it might be required to not look there as some partition info might lurk
there. The bootsector is simply not part of a partition.

Actually, due to complaints about this issue, 0.5b mke2fs will zap the
boot sector when creates the filesystem.
