Struct LinuxRootfs 

pub struct LinuxRootfs {
    pub init_binary: String,
    pub init_config: String,
    pub extra_files: Vec<InitrdFile>,
    pub busybox: Option<String>,
    pub sshd: Option<SshdSpec>,
    pub packages: Vec<GuestPackage>,
    pub name: String,
}

The full recipe for a bootable initrd.

Fields

init_binary: String

init_config: String

extra_files: Vec<InitrdFile>

busybox: Option<String>

Bridge the busybox binary into the guest. Default: busybox from nixpkgs.

sshd: Option<SshdSpec>

Optional sshd setup. When Some, the emitted runCommand pulls the full pkgs.openssh closure into root/nix/store/, symlinks /bin/sshd + /bin/ssh-keygen, generates a host key at build time, and writes /etc/ssh/{sshd_config, authorized_keys}. The caller is responsible for adding the sshd service to init_config.

packages: Vec<GuestPackage>

Userspace packages to install in the guest. Each package’s closure is copied into root/nix/store/; bin entries land in /bin/.

name: String

Name baked into the output derivation.

Implementations

impl LinuxRootfs

pub fn new( init_binary: impl Into<String>, init_config: impl Into<String>, ) -> Self

pub fn with_name(self, n: impl Into<String>) -> Self

pub fn with_file( self, path: impl Into<String>, content: impl Into<String>, ) -> Self

pub fn with_file_from_store( self, path: impl Into<String>, store_path: impl Into<String>, ) -> Self

pub fn without_busybox(self) -> Self

pub fn with_sshd(self, spec: SshdSpec) -> Self

Bake openssh + sshd_config + authorized_keys + a generated ed25519 host key into the initrd.

pub fn with_package(self, attr_path: impl Into<String>) -> Self

Add one userspace package. bin_names empty means “symlink every bin/* entry into /bin/”.

pub fn with_packages<I, S>(self, attrs: I) -> Self

where I: IntoIterator<Item = S>, S: Into<String>,

Add many packages at once.

pub fn derivation(&self) -> Derivation

Produce the tatara Derivation whose realization is the initrd.cpio.gz.

pub fn to_nix_expr(&self) -> String

Emit the full runCommand Nix expression.

Trait Implementations

impl Default for LinuxRootfs

fn default() -> Self

Returns the “default value” for a type.
