What about using callPackage to import qemu directly from the old nixpkgs? Pros: sharing dependencies (e.g. glibc) with other packages in
nixpkgs-unstable. Cons: re-building qemu required for every flake user. Maybe a binary cache (e.g. cachix) can be used, and we can only rebuild riscv32/riscv64 qemu targets.let qemu7 = self.callPackage "${nixpkgs-qemu7}/pkgs/applications/virtualization/qemu" { inherit (self.darwin.apple_sdk.frameworks) CoreServices Cocoa Hypervisor; inherit (self.darwin.stubs) rez setfile; inherit (self.darwin) sigtool; qemu = qemu7; # Reduces the number of qemu source files from ~10000 to ~2600 source files. hostCpuTargets = ["riscv64-softmmu" "riscv32-softmmu"]; };I guess this diff is what you means. by the ways, what is the reason of
inherit (self.darwin.stubs) rez setfileandinherit (self.darwin) sigtool? Which i have check some code using it, but haven't ideas about this, it's necessary dependence or optimization in macOS?Sorry about i have no ideas about macOS, but it seems sigTool is using for signature and database management tool, I can't understand the use of this place.

No idea. I just copied these lines from nixpkgs:
@gjz010 would you be interested in another one?
Another rust operating system support Multiple Architectur, which flake haven't complete yet.
