Hi,
I am not 100% if I got your point.
If you want to speed-up the ptxdist build you may have a look at https://www.ptxdist.org/doc/daily_work_section.html#using-pre-built-archives
If you want to create an environment for application developers where they can compile the application without ptxdist,
you just need to provide the `platform-XXX/sysroot-target` and a bunch of variables depending on the build-system.
Regards, Denis

What exactly do you want to do in the docker? Just create images? Compile
selected packages?

If a package is done and not rebuilt, then you don't need the corresponding
directory in build-target / build-host and packages/.

There is a dependency on the source archive. However, it's a "existence
only" dependency, so the timestamp of the file does not matter. It should
be possible to replace all the source archives with empty files.

I think, with the right tricks this should already be possible. But only
if you are very careful. As soon as some dependency triggers a rebuilt then
it will break apart with strange errors. And you'll probably need to
rebuild most of the BSP. And changing that is quite complex.
