I think something could very easily break between step 2 and 3 depending
on the environment the user has set up.

I suggest:

'tftp' miniroot ( floppy contains network program which works over apple talk
                tcp/ip etc. and moves the appropriate binary file from
                another machine ( or extract from install media 
                (compressed) thus precluding using the network for this user.)

miniroot boots
formats and create partitions
mount_nfs or mount_applefs or ...
create directories and install files... via A/UX type cpio or tar which
can handle multiple file types (Mac, Unix, DOS)
