Basically a synonym for ibs=1 I guess, but maybe with an optimized
implementation.

How do I remove any input block boundaries and force strict blocking on
the output side? According to the man page "dd obs=XXX of=/dev/rXXXX" 
is not enough, since input blocks need not be multiples of 512 byte.

dd obs=XXX ibs=1 of=/dev/rXXXX

should work, but would be realy inefficient, wouldn't it?
