Good!! And thanks :)

And is the lawyer specialized in patent laws??

If it's x86 vs. AMD64, then the installer can already do most of the
work, and it can ask the user to insert the right 2nd/3rd/etc CD/DVD.

Don't you think that taking a CD/DVD to each workstation and start the
installation or upgrade is so old school??

Software updates inside those companies are done via the internet
network, and it does not matter whether the DVD can handle all the
architectures or not.

And the idea of a general-purpose release might not work. As 90% of
the users are using a single architecture (I count AMD64 as x86 with
"some" extensions...), we won't get the benefits so having the extra
code in the kernel and the userspace. Most of the shipped commercial
binaries will be x86 anyways -- and as Alan stated, the packaging
system is already doing most of the work for us already (I don't
recall providing anything except the package name when I do apt-get).

For embedded systems, they wanted to take away all the fat more than
shipping a single app.

The kernel part refers to kernel modules.

But yes, binary compatibility was a real pain when I "really" (played
with it in 1995, didn't really like it at that time) started using
Linux in 1997. However, I think the installer/package manager took out
most of the burden.
