Ooops... two problems:

a) it would  have to be /dev/rsd0a, and tbe bootblock is 8k (16
disk blocks) big.

b) you would need to fix the bootblock's checksum, too.

So you better build a new one.

2nd problem, thats what the "boot to single user" is about:

if at security level > 0, you can't write to a partition (even the 
raw partition) thats already mounted.

Sorry, no better answer.
