Brian, do you know why parted adds the boot code but fdisk does not?
Maybe we should consider removing it?  It's only use is to chain load
the "active partition" boot loader.  I can only think of three times
this is going to be used:

1) Booting DOS/Windows: they have commands to add the boot code after
the fact, and normally they would partition the disk first.

2) Booting with LILO installed to a partition: LILO had a switch to
write the MBR boot code if you ever wanted to do this and anyone still
uses LILO.

3) Booting with GRUB installed to a partition: GRUB strongly recommends
installing to the MBR instead, and if you really must put it in a
partition, and don't already have MBR boot code, you can use LILO to add it.
