wsl-firstboot

Description

NOTE: This is an adjusted version of https://github.com/openSUSE/jeos-firstboot, for use with WSL. It SHOULD NOT be used outside of WSL

wsl-firstboot allows initial configuration and adjustments of a Linux system using text based dialogs.

It is a lightweight and customisable firstboot wizard that allows to set basic system settings during and after the first boot of an image. Including showing the license and prompt for language, keyboard, timezone, root passsword and network configuration..

This is mainly developed for openSUSE and SUSE Linux Enterprise Server WSL images. For more information visit the JeOS wiki.

Installation

The RPM package is developed in openSUSE OBS devel package

You can also get binaries RPM for openSUSE flavours at package download

Usage

wsl-firstboot is used as two systemd services wsl-firstboot.service and wsl-firstboot-snapshot, for using it you need to copy the appropriate service files and enable it.

You can check the example in the RPM package for installation.

The service is controlled by a file, so after installing it you should be sure that your system is configured appropriately

# Enable wsl-firstboot
mkdir -p /var/lib/YaST2
touch /var/lib/YaST2/reconfig_system

systemctl mask systemd-firstboot.service
systemctl enable wsl-firstboot.service

Beside the service that runs on firstboot there is also a tool to change configuration in a running system, this will also be installed and available as wsl-config

wsl-config usage:

Usage: wsl-config [OPTION...] [CONFIG_NAME]
Configure system settings using an interactive dialog

  -h                        Show this usage help
  locale                    Show configuration for locale
  keytable                  Show configuration for keyboard
  timezone                  Show configuration for timezone
  password                  Show configuration for password
  network       (removed)   Show configuration for network
  raspberrywifi (removed)   Show configuration for raspberrywifi
  registration              Use SUSEConnect, if required
  switch                    Choose SLES or SLED, if required

Additional modules (like raspberrywifi) are shown if proper prerequisites are met.

If no parameter is given it shows a dialog for selection.

Writing modules

wsl-firstboot can be extended using modules written in bash placed in /usr/share/wsl-firstboot/modules/ or /etc/wsl-firstboot/modules/. Modules in /etc/wsl-firstboot/modules/ will be preferred. If a link to /dev/null is encountered, the module is skipped.

The basename of the module file is its name. It is used as prefix of properties and hooks. It is also used as argument to wsl-config when calling the module directly.

Properties

# Shown in wsl-config for module selection
yourmodule_title="Title of your module"
# Shown in wsl-config --help
yourmodule_description="Show an awesome dialog with a nice button"
# Priority of the module. Modules with higher priority are run later in wsl-firstboot and shown below in wsl-config.
# The default is 50.
yourmodule_priority=50

Hooks

# Runs if called by wsl-firstboot, currently after systemd-firstboot is called
# (that should probably be changed)
yourmodule_systemd_firstboot() { }
# Runs if called by wsl-firstboot, after all systemd_firstboot hooks.
yourmodule_post() { }
# Runs if called by wsl-config
yourmodule_wsl_config() { }
# Runs at the end of wsl-firstboot just before exiting.
yourmodule_cleanup() { }
