## Using your own kexec image
|
||||||
|
|
||||||
|
By default `nixos-remote` will download the kexec image from [here](https://github.com/nix-community/nixos-images#kexec-tarballs).
|
||||||
|
It is also possible to provide your own by providing a file to `--kexec`. The image will than uploaded prior to executing.
|
||||||
|
|
||||||
|
``` shell
|
||||||
|
nixos-remote \
|
||||||
|
--kexec "$(nix build --print-out-paths github:nix-community/nixos-images#packages.x86_64-linux.kexec-installer-nixos-unstable)/nixos-kexec-installer-x86_64-linux.tar.gz" \
|
||||||
|
--flake 'github:your-user/your-repo#your-system' \
|
||||||
|
root@yourip
|
||||||
|
```
|
||||||
|
|
||||||
|
`--kexec` can be useful for example for aarch64-linux, where there is no
|
||||||
|
pre-build image. The following example assumes that your local machine can
|
||||||
|
build for aarch64-linux either natively or through a remote builder
|
||||||
|
|
||||||
|
``` shell
|
||||||
|
nixos-remote \
|
||||||
|
--kexec "$(nix build --print-out-paths github:nix-community/nixos-images#packages.aarch64-linux.kexec-installer-nixos-unstable)/nixos-kexec-installer-aarch64-linux.tar.gz" \
|
||||||
|
--flake 'your-flake#your-system' \
|
||||||
|
root@yourip
|
||||||
|
```
