What's wrong with leaving the message in the -v output? After all, it's debugging info. > I propose an option to turn OFF write allocation instead of just one to turn > it on.

You'd better pass the spacing issue past bde. Certainly it mathes the other messages. On the whole, I suppose this is reasonable info, but I wonder if we're not tending towards too much information anyway. I needed to increase the MSGBUF_SIZE on some machines just to get the total content of a non-verbose boot.
