* Fix example in README.md
The minimal example was missing the wrapping `disko.devices` attributes which resulted in the following error message:
```
error: attribute 'disko' missing
at /nix/store/1lvj5ry4y5qyis40qcch1csf8h86z8bk-disko/share/disko/default.nix:10:49:
9| # _file = toString input;
10| imports = lib.singleton { disko.devices = cfg.disko.devices; };
| ^
11| options = {
Did you mean disk?
```
* Increase ESP size
From 100M to 500M

|
||
NixOS is a Linux distribution where everything is described as code, with one
|
||
exception: during installation, the disk partitioning and formatting are manual
|
||
steps. **disko** aims to correct this sad 🤡 omission.
|
||
|
||
This is especially useful for unattended installations, re-installation after a
|
||
system crash or for setting up more than one identical server.
|
||
|
||
## Overview
|
||
|
||
**disko** can either be used after booting from a NixOS installer, or in
|
||
conjunction with [nixos-anywhere](https://github.com/numtide/nixos-anywhere) if
|
||
you're installing remotely.
|
||
|
||
Before using **disko**, the specifications of the disks, partitions, type of
|
||
formatting and the mount points must be defined in a Nix configuration. You can
|
||
find [examples](./example) of typical configurations in the Nix community
|
||
repository, and use one of these as the basis of your own configuration.
|
||
|
||
You can keep your configuration and re-use it for other installations, or for a
|
||
system rebuild.
|
||
|
||
**disko** is flexible, in that it supports most of the common formatting and
|
||
partitioning options, including:
|
||
|
||
- Disk layouts: GPT, MBR, and mixed.
|
||
- Partition tools: LVM, mdadm, LUKS, and more.
|
||
- Filesystems: ext4, btrfs, ZFS, bcachefs, tmpfs, and others.
|
||
|
||
It can work with these in various configurations and orders, and supports
|
||
recursive layouts.
|
||
|
||
## How to use disko
|
||
|
||
Disko doesn't require installation: it can be run directly from nix-community
|
||
repository. The [Quickstart Guide](./docs/quickstart.md) documents how to run
|
||
Disko in its simplest form when installing NixOS.
|
||
|
||
For information on other use cases, including upgrading from an older version of
|
||
**disko**, using **disko** without NixOS and downloading the module, see the
|
||
[How To Guide](./docs/HowTo.md)
|
||
|
||
For more detailed options, such as command line switches, see the
|
||
[Reference Guide](./docs/reference.md)
|
||
|
||
To access sample configurations for commonly-used disk layouts, refer to the
|
||
[examples](./example) provided.
|
||
|
||
## Sample Configuration and CLI command
|
||
|
||
A simple disko configuration may look like this:
|
||
|
||
```
|
||
{ disks ? [ "/dev/vdb" ], ... }: {
|
||
disko.devices = {
|
||
disk = {
|
||
vdb = {
|
||
device = builtins.elemAt disks 0;
|
||
type = "disk";
|
||
content = {
|
||
type = "gpt";
|
||
partitions = {
|
||
ESP = {
|
||
size = "500M";
|
||
content = {
|
||
type = "filesystem";
|
||
format = "vfat";
|
||
mountpoint = "/boot";
|
||
};
|
||
};
|
||
root = {
|
||
size = "100%";
|
||
content = {
|
||
type = "filesystem";
|
||
format = "ext4";
|
||
mountpoint = "/";
|
||
};
|
||
};
|
||
};
|
||
};
|
||
};
|
||
};
|
||
};
|
||
}
|
||
```
|
||
|
||
If you'd saved this configuration in /tmp/disko-config.nix, and wanted to create
|
||
a disk named /dev/nvme0n1, you would run the following command to partition,
|
||
format and mount the disk.
|
||
|
||
```
|
||
$ sudo nix run github:nix-community/disko -- --mode disko /tmp/disko-config.nix --arg disks '[ "/dev/nvme0n1" ]'
|
||
```
