From 546aec2dd673375b176313efbc3150f607e196de Mon Sep 17 00:00:00 2001 From: wes Date: Sun, 16 Nov 2003 07:08:27 +0000 Subject: Write the UFS2 superblock with a 'BAD' magic number at the beginning of newfs, to signify the newfs operation has not yet completed. Re- write the superblock with the correct magic number once all of the cylinder groups have been created to show the operation has finished.
