In comparision to "dd if=/dev/XXX of=/dev/XXX" the command structure you
propose seems very complex. dd also gets all files with permissions
down to the bit level and will not cross mount points. The beauty of
Unix is that you can dream up ever more complex ways of doing what is
easily accomplished. However, the orginal mindset of Unix, other than
for playing games, was to make small tools that were easy to use and be
compiled into larger tools when that was necessary. And just in case
you want dd to be a more complex command, there are many switches which
can be set.
