We would like to build these with Hydra but we do not currently have a
Hydra to build them with conveniently.

Cross-compiled builds are available for ARMv6 (`armv6l-linux`) and ARMv7 (`armv7l-linux`). ### Cross compiling using the Lix flake
Add more [system types](#system-type) to `crossSystems` in `flake.nix` to bootstrap Nix on unsupported platforms.
Lix can also be easily cross compiled to the following arbitrarily-chosen system doubles, which can be useful for bootstrapping Lix on new platforms.
These are specified in `crossSystems` in `flake.nix`; feel free to submit changes to add new ones if they are useful to you.
- `armv6l-linux`
- `armv7l-linux`
- `riscv64-linux`
For example, to cross-compile Lix for `armv6l-linux` from another Linux, use the following:
```console
$ nix build .#nix-armv6l-linux
```
It's also possible to cross-compile a tarball of binaries suitable for the Lix installer, for example, for `riscv64-linux`:
```console
$ nix build .#nix-riscv64-linux.passthru.binaryTarball
```
