AIUI they don't actually work properly with PHP 8 and/or needs
significant porting effort. The references are:

Hi Neal,
Can you add more info on this? which module are distributed
and how they are consumed?
In fact so does libnbd, so the problems were the same. Nir
(CC'd)
can talk a bit more about this. My interest in golang is >< small.
LIbnbd Go bindings are published now in the standard way using
Go proxy server. Developers can use:
Import "libguestfs.org/libnbd"
Like any other dependency (e.g. from github.com, etc).
The go tools will find the package proxy server looking at
https://libguestfs.org/libnbd
pointing the tools to the proxy server at
https://download.libguestfs.org/libnbd/golang
We use this script to prepare the files for the web server
for every release:
https://gitlab.com/nbdkit/libnbd/-/blob/master/golang/make-dist.sh
The same file structure on the web server can be used with
a "file:///" URL, if the files are packaged for a distribution
in a known location, users can use something like:
GOPROXY=file:///path/to/go/modules
See https://golang.org/ref/mod#environment-variables
But I think this is best discussed here:
https://groups.google.com/g/golang-nuts
I'm working on another module that will likely be published in the
same way, and I also want to package it for Fedora, please CC
me on related discussions.
