Thank you for that hint. (It looks like I overlooked that `platform` is
used beforehand to set `MTX_PLATFORM` and `os.platform`. So `--platform`
does not seem to be honored all the way.)

Your hint gave me more output but left me with a non-working system.

        $ HOSTTYPE="linux" mtxrun --verbose --script ./bin/mtx-update.lua --update --make --force --engine=all --context=beta --platform="linux" --texroot=/opt/context/tex

        MTXrun | kpse fallback with progname 'context' initialized in 0 seconds

The whole output with `--verbose` is attached (compressed, as the other
message did not make it through).

Again there is the following line in there.

        MTXrun | resolvers: skipping list of '/opt/context/tex/texmf-linux-64' (cached)

I also tried to prefix the last two command with `HOSTTYPE="linux"`.

Any ideas?


Thanks,

Paul
