Well, it would be nice to know what you're
really trying to do.
What's the hardware? If the file system is UFS, it's unlikely to be a
good fit for Linux. I'd say "try FreeBSD", but without knowing more
about your software and hardware, it's not clear if that would be any
better. Google suggests that it runs on ARMs. Is that correct?
The hardware is an obscure british platform from back when the ARM was
young. - The Archimedes.
The CPU is the ARM2 or 3 (either work) and the systems have SCSI,
ethernet, and (up to) 16Mb of RAM.
I dont actually know what the filesystem is, but my guess is UFS based
on the newfs command in the mkkernel script, and a rumour it is BSD
derived. I have everything from a machines filesystem in a
tarball.
I simply have no bootdisk, and cant create one without a suitable newfs

Take a look at James Carter's page at

James and I worked this out when we rescued half-a-dozen R260's in various
states of disrepair and with various not-quite-complete copies of RISC iX.
is it possible for someone else to make a filesystem
image for me that I
could dd onto a floppy? I suspect that this system uses an old variant
of ufs.
It is a standard 4.3 filesystem (at least for the verison for an R260). It
even says so when it boots:
RISC iX Release 1.2
ARM3 processor, cache enabled
...
...
Root fstype 4.3, name /dev/sd0a
Swap fstype spec, name /dev/sd0S
...
One of us could copy some stuff for you. I'm not sure you'd be able to get
what you need onto a single floppy, though. That's not how Acorn did it.
We'd certainly be willing to help, especially if you have any RISC iX stuff
we're missing.

wont I need a working installation first?
Thats good to know - linux can actually write to that (although attempts
so far have led to kernel panics!)
Do you know of generic source for mkfs ?

did you see the scripts I attached?
Apparently the create 3 floppies, which can be used to install a system.

You're certainly welcome to any stuff I have.
Id be eternally grateful if you could run those 3 scripts on a riscix
machine though (even better if you could use a disc image - can risciX
do loopback mounted filesystems?)
once you have 3 floppies [which can be imaged], or 3 disc images, could
you email them to me?
