AFAI understood the question your (Karl) answer is wrong, you mixed our
updates of tlnet and the updates of the client.

Yes, calling
	tlmgr update --all
DOES update texlive.infra and bin-texlive, that is right.

The only thing is that *we* don't update these packages *from* the svn
repository *to* the tlnet automatically, only after testing and manual

After you have done it *once* now you don't have to do it at all
manually. Normal update procedure will bring it.

The reason to do is separately the first time is that the tlmgr as
shipped on DVD is a bit buggy (to be friendly), better it is not very
much forgiving to networking errors etc.

I guess Karl had all that in mind when writing:

In this respect Karl is right. The reason is that bin-texlive and
texlive.infra are tightly coupled. We did the error to not merge them
into one package for the DVD, our failure, I didn't think of that. Now,
if one of the two is updated and the other not it might be a real

BTW Karl, we could ship tlmgr and the perl modules in *both*
texlive.infra and bin-texlive. Slight duplication but making life more
safe... WDYT?

Yeah, that is fine. Thanks Karl.
