Sure it does, because it means you can simply commit a change to the default assignment for that sysctl rather then backing the whole thing out to unbreak the general developer community. That saves a lot of time and removes the 'oh hell, I have to track this down quickly!' pressure. Sometimes features in early boot can be adjusted by breaking into DDB and w/l changing the sysctl variable, but perhaps not in this case. -Matt Matthew Dillon <[EMAIL PROTECTED]> To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message
