It's there fore cruft like disklabel and partitioning programs that operate on the whole disk, but don't use ioctl()'s to do it (obviously, if a label is useful, the kernel already has a model of it, and user space code dependent on c is just duplicating effort). > Is 'd' still magic too? I seem to recall that it was magic once upon > a time. But not any more, right? The d partition was magic because it used to span the whole FreeBSD area. Now we trust the DOS parittion table (or ourselves, if we are in "dangerously without a second stage boot record" mode. > Also, 'b' used to be magic (reserved for swap) in some Unix variants. > Not for us, right? See the disklabel. The use of swap is dictated by the "partition" type field.
