   In that case, "conv=osync" is not needed, and the following command
   should work:
   
   	gzip -dc image.gz | dd of=/dev/rwd0d obs=16k

   And, hmm, I guess GNU gzip is doing buffering at output side,
   but gzip in -current does not.
   
   Matt,
   Isn't it better to do the buffering for compatibility with GNU gzip?

hmmm.  gnu gzip appears to write in 32k blocks, mrg gzip does it
in 64k blocks.  soda, do you think i should change this to 32k?

jukka, if you change gzip.c #define BUFLEN to (32 * 1024) can
you see if that helps?
