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

Well, how about this: Do a mkfs on a floppy, chroot to it, and make an etc directory, in which you put an fstab. >I did a mkfs for a 102400 block file sysetem, and that seemed to >work.

You can get by with about 45 MB, but I can't say exactly how much. This is without the games but with the manuals. BTW, I strongly recommend that you try to make a BSD FS. It really is much faster. If my idea doesn't work, it might well be worth the time to go to your dealer and get it done right. In fact, what with your cpio problem, you probably don't have much choice in the matter... --- Alexis Rosen Owner/Sysadmin, PANIX Public Access Unix {cmcl2,apple}!panix!alexis
