This is harmless overhead for > the UFS1_ONLY case, but sufficient for boot2(UFS1+2). Well, except that now those 4 sectors that are the start of the BSS for boot2 aren't zero'd like they used to be but now contain garbage data. Most C programs don't work well when their BSS isn't zero. I think trying to fit UFS1 and UFS2 support into the old boot1 and boot2 just isn't going to work. -- John Baldwin <jhb@FreeBSD.org> <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve!" - http://www.FreeBSD.org/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe cvs-all" in the body of the message
