Greetings, all!
Strange phenomenon.
I have a multi-boot system with two 8G drives.  FBSD resides on ad0s3.
Similarly, ad1s3 is unused, and I wsih to use it for /usr/local BUT
fdisk will not allow me to partition that part of the disk for FBSD use.  :-(
Why?
Even more important, how do I overcome the limitation?
