What is the point of copying the MBR
if you then use LILO or grub-install to write it out again?
IMO there is zero probability of an MBR from one disk working on another,
so as I said it seems entirely pointless to copy it.
Of course there is some point in copying the MBR with dd
for later re-copying to the same disk if something goes wrong,
particularly if you are using an obsolete boot loader like LILO.

On my system (Fedora-1) cp -a already includes -r = --recursive .
