When this is done on a system where ConTeXt first came with a TeXlive or
teTeX installation, will this replace existing files, or will it put the
updated new files in TEMXFLOCAL or TEXMFHOME, respectively? Ah, I think
you have answered this already below.

So I guess this is the call that would also be needed if the update
itself goes via a package management, i.e. if one installs a new version
of the Debian ConTeXt package.

So I guess TeXlive (and the existing teTeX packages within
Linux/BSD/... distributions) should do that, so that modern ConTeXt just
works.

It might be possible by setting, in texmf.cnf,
TEXFORMATS.xetex = .;$TEXMF/web2c{xetex,}
TEXFORMATS.pdftex = .;$TEXMF/web2c{pdftex,}
and so on. I'm not sure, however; this of course depends on which
progname ConTeXt uses (so it might need to be TEXFORMATS.cont-xetex or
whatever).

I think, with the TEXFORMATS.$engine setup working, it should be
possible to use both, fmtutil and texexec, and get the same formats -
texexec might still be better in doing other update tasks.

This also sounds like a bug in TeXlive/teTeX.

So this means -update will always try to overwrite an existing
installation, and not automatically search for a writable directory
that's earlier in the TEXMF path? Even not as a fallback? This sounds
as if this tool could be improved.

I think it does help a lot, and we can work from there, testing with the
Debian ConTeXt package.
