There are options to texexec for using different tex engines. Perhaps
they changed the default tex engine from pdftex to luatex. Can you try
running it with --pdftex or --xetex (or whatever the options are if they
have changed, man texexec should tell you). Also, it's possible that the
script to run ConTeXt (even for MkII) changed to "context" rather than
"texexec" (though I have doubts for this).

Does luatex actually get installed by texlive? If so, perhaps we can
hunt down whatever config value is causing ConTeXt to not find it. If
it's not being installed, perhaps we can fix INSTALL to make it install
it (perhaps optionally so via CONFIGURE?).

In fact, the good old tetex used /usr/local/share/texmf, and I prefer
that method myself. I don't really like the texlive way of handling
things, but I guess I'm just old-school. However, TeX and FHS don't
really go together in all respects. TEXMFSYSCONFIG is not actually
"config" files in the sense of what would typically go in /etc (in my
own /usr/share/texmf-conf, it is currently completely empty except for a
single ls-R file generated automatically by texhash/mktexlsr). The real
config file is texmf.cnf (and others in /usr/share/texmf/web2c/), and
that *must* reside in the system texmf tree. TeX wasn't designed when
FHS existed, and indeed runs on systems other than linux, so it uses its
own notion of directory locations via kpathsea (kpsewhich and etc.), and
the tex engines use this to find all their necessary files, including
texmf.cnf. Changing tex to really use /etc would require hacking it
quite a bit. In other words, setting TEXMFSYSCONFIG=/etc/texmf would
only be purely cosmetic and not really achieve any compliance.
