How do I do newfs on an HD80SC with a 50 meg /root&/usr part?

I would like to alter the default partitioning of my internal 80
meg hard disk on my Mac II cx. I need to run National Instruments'
Labview II, which does not coexist happily under A/UX, requiring 12
megs of Mac filesystem to load. The system came with A/UX
pre-installed, so it looks like some creativity may be required.
Hence I have embarked on the interesting trail of constructing a
new Unix file system of the requisite size. Let me reoucont what
I've done so far.
0. do a find / -name "*" -print | cpio -ocB > /dev/rfloppy0 and
make back-ups of everything in the Mac partition.
1. Use Sash to set up new partitions:
51200 Kb /root&/usr slice
8192 Kb swap slice
3072 Kb escatology slice
~17516 Kb Mac partition (forget the exact number at the
moment, but it was whatever was
leftover after setting up the A/UX
partitions)
2. Reload the system folder, Mac bin, escher, read_disk, escher,
and A/UX startup files from backups that I'd made.
3. while ( 1 ) { scratch head; hmmmm.... }
4. At this point I called Apple tech support for suggestions. I
had tried to do a newfs for rdsk/c0d0s0, but ran into the catch-22
that there t'aint no /etc/disktab from which to get parameters.
Tech support wasn't sure either, but suggested going with a mkfs
for a Sys V file system.
I did a mkfs for a 102400 block file sysetem, and that seemed to
work. I think I am running into problems because the Sys V file
system doesn't get along with some of the long names in the cpio
archive from the original Berkeley file system.
The A/UX dealer in the area is about a 50 mile drive from here, so
I thought I'd like to do the restore myself (and get a file system
education at the same time) if possible. The other question is, "Is
it possible to have anynthing other (i.e. smaller) than the 55 meg
default /root&/usr partition size and still do the canned install?"
(if I give up and go to the dealer for a re-load)
Thanks a bunch,
Bill
