was the only difference between 1 and 1.2 the kernel?

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

do loopback mounted filesystems?)
once you have 3 floppies [which can be imaged], or 3 disc images, could
you email them to me?
