A small detail, why do we still have to specify the blocksize (bs=1m) to dd. Can't it have a better default than 512 bytes.

In most cases, 128k is actually the optimal block size, and is (microscopically) faster than 1m. And also uses a tiny bit less ram.
Seems like a good default. I was expecting tons of comments telling me that it had to stay at .5 K for various arcane reasons.
I can't even imagine the suffering with broken shell scripts if the defaults change.
