I guess. There's always some hack to dd me and David O'Brien keep asking about adding- you have to do the DIOCWLABEL. This keeps on getting discussed over and over and over again. Bruce claims to understand all of this- I sure don't. I *do* know that dangerously dedicated disks that are built on i386 aren't readable on alpha (a mistake that linux avoids). I have some mail going back a year saying "this all has to be fixed for 4.0!". Guess what? The story probably is "somebody needs to own the issue" and it hasn't reached a level of pain for me to do that (other things are far more painful). -matt To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
