it>/mnt# newfs -N /dev/ad3s1f | head
/dev/ad3s1f: 36383.7MB (74513744 sectors) block size 16384, fragment
size 2048 using 198 cylinder groups of 183.77MB, 11761 blks, 23552
inodes.
super-block backups (for fsck -b #) at:
160, 376512, 752864, 1129216, 1505568, 1881920, 2258272, 2634624,
3010976, .....
So no luck here :). I've tried adding some fprintf in the newfs code
(like fs_fcg and fs_ncg), but obviously I've did something wrong and
the values don't make any sense.
Thanks,
