[tex-live] share sub-directory

[Karl Berry]

    Is the "share" sub-directory now mandatory, 

There was no such intention.  TL itself has no share/ subdir after all.

    kpathsea: Running mktexfmt latex.fmt

So, the question is why mktexfmt is exiting without making the fmt.  Try
running bash -vx mktexfmt latex.fmt from the shell, for starters.

I can't look at 100+ changes and magically intuit where the problem
might be :).

Best,
