Hello NetBSD'ers

I want to thank everybody for the excellent help 
in the past.  I've got what might be an easy question.

I recently removed/shrunk a Mac HFS partition on my
Quantum 3.2 Fireball drive, leaving a nice 400MB
chunk sitting right next to my /usr NetBSD partition.

It it possible to non-destructively expand my /usr
partition to utilize this new space?

I know that the easy think to do would be to create
a new partition and mount it somewhere underneath
the /usr tree (like /usr/pkg) or something.  I could
also throw /var or /tmp onto the additional partition,
but I'm hoping a little extra work would help later.

I also have a DAT drive (DDS-1?) that I have not used
on NetBSD yet.  I could TAR up /usr to DAT, combine
and reformat my /usr partition, then restore the backup.

Ideas and suggestions?
Thanks,
Roger
