Re: Getting mad on mounting MSDOS partitions

[Jim Razmus <lists@bonetruck.org>]

I think your confusing fdisk and disklabel.  I recommend the man pages on both.  Disklabel is used for carving up space within an "fdisk" partition.  For example, via fdisk you might have 2 partitions on the drive, we'll call them A and B.  Say A is an MSDOS partition of some sort while B is for OpenBSD.  You would then use disklabel to carve up B logically into /, /tmp, /usr, /var, etc.  Follow disklabel with newfs and you now have usable space for OpenBSD.

I'm not sure what your trying to do with disklabel, so I can't answer your question directly...

HTH,
Jim
