Depending on what other (additional) features you're willing to accept, the GoHarbor[0] registry supports pull-through as well as mirroring and other features, it's a nice registry that also supports other OCI stuff like Helm charts, and does vulnerability scanning with "Interrogation Services" like Trivy.
I've been using it at home and work for a few years now, might be a bit overkill if you just want a simple registry, but is a really nice tool for anyone who can benefit from the other features.

Project mention: Arch Linux Now Has a Bit-for-Bit Reproducible Docker Image | news.ycombinator.com | 2026-04-23
For the package management, it depends on the package manager, but most have some mechanism for installing into a root other than the currently running system.
Even without explicit support in the pacakage manager, you could also roll your own solution by running the package manager in a chroot environment, which would then need to be seeded with the package manager's own dependencies, of course (and use user-mode qemu to run non-native executables in the case of cross-architecture builds).
Whether this yields a minimal container when pointed at a repository intended to be used to deploy a full OS is another question, but using a package manager to build a root filesystem offline isn't hard to pull off.
As for how to do this in the context of building an OCI container, tools like Buildah[1] exist to support container workflows beyond the conventional Dockerfile approach, providing easy-to-use command line tools to create containers, work with layers, mount and unmount container filesystems, etc.
