For backwards compatibility, the FreeBSD 4.x kernel would fake up the partition tables so that they would look like old (pre-slicing) FreeBSD partition tables; i.e., the starting offset of the slice would be subtracted from all of the partition offsets on read and added back in on write. The disk partitioning subsystem in 5.x doesn't do this. -GAWollman To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
