I know this has been discussed and after searching this board and the
internet, I have found conflicing answers:

We want to use 2003 RIS to build our servers but dont want RIS to expand the
entire partition? Is there a way to do this w/o being prompted for what
partition to use if I pre-create the partition? Can I set the size of the
partition to use in the sif file? I think my promlem sections are in
[unatended] and [remoteinstall].

Ive attached my sif file.
