Both only touch pkgsStatic builds, which nothing on this host pulls in since qemu-user binfmt was removed; the toplevel drvPath is unchanged. Assisted-by: Claude Code (claude-opus-5-5)
Host - Shoukei
This is NixOS's configuration for my Macbook Pro 2022 M2, 16G RAM.
This laptop joins untrusted networks and uses DHCP by default. On the home Wi-Fi
(shadow_light_ryan) run just shoukei-home-wifi to pin 192.168.5.108; the recipe calls
scripts/shoukei-home-wifi-static.nu, and
vars/networking.nix records the address with homeOnly = true.
x86/x86_64 applications
The M2 uses 16 KiB pages, and FEX does not emulate 4 KiB guest pages, so x86/x86_64 binaries cannot
run directly on this kernel. game/ enables programs.x86-on-arm from
our fork of
rowanG077/nix-x86-on-aarch64, which runs FEX
inside a 4 KiB muvm microVM and registers both ELF handlers:
- run an x86/x86_64 ELF directly, or use
x86-arm run <program>; nix-shell -p x86pkgs.hello --run hellofor the x86 package set;steamandx86-arm-winefor games and Windows programs.
The microVM is capped at 6 GiB (memoryMiB) on this 16 GiB machine, and needs /dev/kvm plus a
running systemd user session. See WORKAROUNDS.md WA-021.
Because the host no longer registers qemu-user binfmt, podman run --platform=linux/amd64, x86
chroots, and local builds of uncached x86 derivations need a remote x86_64 builder (see
WORKAROUNDS.md WA-022).
