Hi, Ken.... If noone is interested, I am interested.

AFIK you cannot make a cd set from a tape set.  The reason is that
the tape and cd xdrtocs are different, the miniroot kernels are different,
and there is a difference in the scripting internally, from what I can
tell.  (Does that sound like I tried that.....(:+{{...).

You can make a later tape from an earlier tape using cd bits, provided
you keep the original boot/kernel/miniroot/xdrtoc files, from the orignal
tape and overlay the actual tarballs with the later cd stuff.  That works.
I had an old 4.1 tape that I upgraded to a minimal 4.1.3 boot tape, by
using the 4.1.3 cd bits and the 4.1 boot bits.

There may be some internal Sun way of doing it, but I have not seen it
from the outside.  Someone mentioned some scripts for that at one time,
but I was never able to follow that up.
