(2) is fine, but I think LSB should also (3)---at least for ia64.
It's important for distributors to agree on the local of (3).  The
current proposal is /emul/ia32-linux.

If that's the idea, good.  From the description that you quoted, it
sounded like the "Alpha case" was there solely for historical
purposes, which would be misleading.  /lib should *always* contain the
"preferred" library format.
