Hi Bruce,

Quite a lot things are wrong here. First the "Introduction"; TeX Live
is not a *forked successor* of teTeX. Secondly,teTeX was never maintained
by TUG (AFAIR). Thirdly: THe "Additional Download" is actual a
*NECESSARY* download.

Did you read the web pages linked from www.tug.org/texlive, esp:

The files in the source tar ball are NOT A TEX SYSTEM!!! How many
times we have to repeat it. They alone are not useful at all.

Thatis right. But the problem is that "having the support files in place"
is a major difficulty.

BTW; did you *EVER* install a TeX Live system yourself?
Before even *THINKING* about writing some packaging and explanation,
please do that:
- grab the network installer from
- unpack and run it
- select "scheme-minimal" (this is what comes closest to your idea
  of "essential" probably)
- start installation
- look at the outcome!!

The "having the support files in place" is not that trivial, you might
take a look at the installer.

Or, since that is actually what you want to do, read
and at the bottom there are some information.

Or look at any of the distributions with packages for TeX Live, Debian,
Suse, Fedora, *BSD, ... they all did their own packaging in different

Run install-tl, and select scheme-minimal.

Not at all. There are many distros packaging TeX Live in different way.
But the difference is that the people packaging TeX Live there have
most of the time *USED* TeX Live before and know about it....
something you seem to completely lack.

No. It clearly states 
	run ./Build
... and if you are able to read the Build script you see that the
build is done out of tree in a sepearte dir.

Because the install is NOT meant to be used that way. For your information
what happens here: 
- we ask builders to run the Build scrip
- then they send us the binaries as put into inst/bin/*arch-os*/
- we put them into the svn archive under Master/bin/*arch-os*/
- people use our installer (install-tl) to install all the files
  (binaries, support, ...), run the necessary scripts, etc.

That is all there is to the sources, there is NO provision to run 
an actual installation in the scripts. Everything related to
	make install
is only to get things in the right format with links etc to the right
dirs, so that it fits into the TeX Live status.

Then *why* do you try to package it???

Why not first simply *install* it?

I assume you also read through all the pages in http://www.tug.org/texlive?

After you have installed, used, checked where and what files are,
you can think about *how* to adapt that for linuxfromscratch.
