This would be really nice to fix eventually.

Hans, we do have all the required files:
    https://distribution.contextgarden.net/setup/openbsd6.5/
    https://distribution.contextgarden.net/setup/openbsd6.5-amd64/
    ...
    https://distribution.contextgarden.net/current/bin/luatex/openbsd6.5-amd64/
    ...
but the problem is that mtxrun knows the platform under the name of
"openbsd-amd64" rather than "openbsd6.5-amd64".


The first-setup.sh script already correctly recognizes the name by
doing the following:

    system=`uname -s`
    case "$system" in
        OpenBSD)
            version=`uname -r`
            platform="openbsd${version}-amd64" ;; # for 64-bit one; a
separate call for 32-bit of course

while mtxrun "ignores" the version name, but also ignores the
parameter being passed as

    mtxrun --script bin/mtx-update.lua --platform=openbsd6.5-amd64

Thanks.

It would be ideal to fix this properly instead, for everyone else.
This is a good recipe for a workaround, but we need something better.

In my opinion this might be best to maybe even fix inside luatex
sources themselves.

This is something that I need to fix independently in the installation
script. Do you have any clue what could be done to make it work
properly on OpenBSD?

PS: Hans, for some reason the 32-bit virtual machine for OpenBSD 6.5
seems broken in a bad way (I doesn't even reach the login screen), no
clue what's wrong, and I don't have extensive experience with OpenBSD
either. I could keep investigating, but I'll probably simply end up
setting up a fresh one. It would be helpful to maybe do some disk
health checks on the server, just in case.
