> The key is hermetically/reproducibly

Why not use VMs? Libvirt is scriptable enough for that. And LXC/Incus can be used if you want the shorter starting time.

Ok, that solves like 20% of the problem. How (and where) are you provisioning these VMs? How are you managing what versions of what are installed on them, and is that process reproducible?

None of this is hard, exactly, but you do have to put in the legwork of doing it, and it's mostly only the big players who've done so.

A lot of VM managers allows to clone from a disk. And some even allows for an overlay layer on top of a read-only disk.

Creating a build machine is not rocket science.

It's not rocket science. As I said, it's a case of doing the legwork. But you do have to actually do the work rather than just handwave it away. Ok, your VM manager allows you to clone from a disk and maybe allows you to have an overlay layer. Great. Now draw the rest of the owl.
