Control over Installation Partition?

[David McNab mcnab@bayarea.net]

     I'm sorry if this is a tiresome question.  I
looked through the archives and FAQ's and saw some
similiar inquiries, but no definitive answer.

     Is there a way to install to a specific disk
"partition" (as in fdisk partition), or do am I forced
to trust the installation program to Do The Right
Thing?

     I want to install to the end of the second of my
two SCSI disks (I have no IDE disks).  The disk in
question currently has three "fdisk partitions".  The
first two are occupied with MSDOS and FreeBSD, but the
third comprises the unused remainder of the disk.  I
would like to install to the third partition.

     Is there a way to do this explicitly?  Or do I
delete the empty third partition and then trust the
installation to end up in the right place, after the
two occupied partitions?
