It performs the following steps: +. +.Bl -enum +.It +It copies Nix and its dependencies to +.Pa /mnt/nix/store Ns +\&. +. +.It +It runs Nix in +.Pa /mnt +to build the NixOS configuration specified in +.Pa /mnt/etc/nixos/configuration.nix Ns +\&. +. +.It +It installs the current channel +.Dq nixos +in the target channel profile (unless +.Fl -no-channel-copy +is specified). +. +.It +It installs the GRUB boot loader on the device specified in the option +.Va boot.loader.grub.device +(unless +.Fl -no-bootloader +is specified), and generates a GRUB configuration file that boots into the NixOS +configuration just installed. +. +.It +It prompts you for a password for the root account (unless +.Fl -no-root-password +is specified). +.El +. +.Pp +This command is idempotent: if it is interrupted or fails due to a temporary +problem (e.g. a network issue), you can safely re-run it. +. +. +. +.Sh OPTIONS +.Bl -tag -width indent +.It Fl -verbose , v +Increases the level of verbosity of diagnostic messages printed on standard +error. For each Nix operation, the information printed on standard output is +well-defined; any diagnostic information is printed on standard error, never on +standard output. +.Pp +Please note that this option may be specified repeatedly. +. +.It Fl -root Ar root +Defaults to +.Pa /mnt Ns +\&. If this option is given, treat the directory +.Ar root +as the root of the NixOS installation. +. +.It Fl -system Ar path +If this option is provided, +.Nm +will install the specified closure rather than attempt to build one from +.Pa /mnt/etc/nixos/configuration.nix Ns +\&. +.Pp +The closure must be an appropriately configured NixOS system, with boot loader +and partition configuration that fits the target host. Such a closure is +typically obtained with a command such as +.Ic nix-build -I nixos-config=./configuration.nix '<nixpkgs/nixos>' -A system --no-out-link Ns +\&. +. +.It Fl -flake Ar flake-uri Ns # Ns Ar name +Build the NixOS system from the specified flake. The flake must contain an +output named +.Ql nixosConfigurations. Ns Ar name Ns +\&. +. +.It Fl -channel Ar channel +If this option is provided, do not copy the current +.Dq nixos +channel to the target host. Instead, use the specified derivation. +. +.It Fl I Ar Path +Add a path to the Nix expression search path. This option may be given multiple +times. See the +.Ev NIX_PATH +environment variable for information on the semantics of the Nix search path. Paths added through +.Fl I +take precedence over +.Ev NIX_PATH Ns +\&. +. +.It Fl -max-jobs , j Ar number +Sets the maximum number of build jobs that Nix will perform in parallel to the +specified number. The default is 1. A higher value is useful on SMP systems or +to exploit I/O latency. +. +.It Fl -cores Ar N +Sets the value of the +.Ev NIX_BUILD_CORES +environment variable in the invocation of builders. Builders can use this +variable at their discretion to control the maximum amount of parallelism. For +instance, in Nixpkgs, if the derivation attribute +.Va enableParallelBuilding +is set to true, the builder passes the +.Fl j Ns Va N +flag to GNU Make. The value 0 means that the builder should use all available CPU cores in the system. +. +.It Fl -option Ar name value +Set the Nix configuration option +.Ar name +to +.Ar value Ns +\&. +. +.It Fl -show-trace +Causes Nix to print out a stack trace in case of Nix expression evaluation errors. +. +.It Fl -keep-going +Causes Nix to continue building derivations as far as possible in the face of failed builds. +. +.It Fl -help +Synonym for +.Ic man nixos-install Ns +\&. +.El +. +. +. +.Sh EXAMPLES +A typical NixOS installation is done by creating and mounting a file system on +.Pa /mnt Ns +, generating a NixOS configuration in +.Pa /mnt/etc/nixos/configuration.nix Ns +, and running +.Nm Ns +\&.
