Re: File systems on 4k sector devices?

        Hello.  I've not tried this, but what if you use the -S flag to newfs
to help it figure out what the sector size is?  I've found that newfs seems
to have trouble extracting pertinent details from the disklabel in
NetBSD-5.  I've worked around this problem with flags to newfs with good
effects.
