systemd Developer Lennart Poettering lennart@poettering.net systemd-firstboot 1 systemd-firstboot systemd-firstboot.service Initialize basic system settings on or before the first boot-up of a system systemd-firstboot OPTIONS systemd-firstboot.service systemd-firstboot initializes the most basic system settings interactively on the first boot, or optionally non-interactively when a system image is created. The service is started if ConditionFirstBoot=yes is satisfied. This essentially means that /etc is empty, see systemd.unit5 for details. The following settings may be set up: The system locale, more specifically the two locale variables LANG= and LC_MESSAGES The system keyboard map The system time zone The system host name The machine ID of the system The root user's password Each of the fields may either be queried interactively by users, set non-interactively on the tool's command line, or be copied from a host system that is used to set up the system image. If a setting is already initialized, it will not be overwritten and the user will not be prompted for the setting. Note that this tool operates directly on the file system and does not involve any running system services, unlike localectl1, timedatectl1 or hostnamectl1. This allows systemd-firstboot to operate on mounted but not booted disk images and in early boot. It is not recommended to use systemd-firstboot on the running system while it is up. The following options are understood: --root=root Takes a directory path as an argument. All paths will be prefixed with the given alternate root path, including config search paths. This is useful to operate on a system image mounted to the specified directory instead of the host system itself. --locale=LOCALE --locale-messages=LOCALE Sets the system locale, more specifically the LANG= and LC_MESSAGES settings. The argument should be a valid locale identifier, such as de_DE.UTF-8. This controls the locale.conf5 configuration file. --keymap=KEYMAP Sets the system keyboard layout. The argument should be a valid keyboard map, such as de-latin1. This controls the KEYMAP entry in the vconsole.conf5 configuration file. --timezone=TIMEZONE Sets the system time zone. The argument should be a valid time zone identifier, such as Europe/Berlin. This controls the localtime5 symlink. --hostname=HOSTNAME Sets the system hostname. The argument should be a host name, compatible with DNS. This controls the hostname5 configuration file. --machine-id=ID Sets the system's machine ID. This controls the machine-id5 file. --root-password=PASSWORD --root-password-file=PATH Sets the password of the system's root user. This creates a shadow5 file. This setting exists in two forms: --root-password= accepts the password to set directly on the command line, and --root-password-file= reads it from a file. Note that it is not recommended to specify passwords on the command line, as other users might be able to see them simply by invoking ps1. --prompt-locale --prompt-keymap --prompt-timezone --prompt-hostname --prompt-root-password Prompt the user interactively for a specific basic setting. Note that any explicit configuration settings specified on the command line take precedence, and the user is not prompted for it. --prompt Query the user for locale, keymap, timezone, hostname and root password. This is equivalent to specifying --prompt-locale, --prompt-keymap, --prompt-timezone, --prompt-hostname, --prompt-root-password in combination. --copy-locale --copy-keymap --copy-timezone --copy-root-password Copy a specific basic setting from the host. This only works in combination with --root= (see above). --copy Copy locale, keymap, time zone and root password from the host. This is equivalent to specifying --copy-locale, --copy-keymap, --copy-timezone, --copy-root-password in combination. --setup-machine-id Initialize the system's machine ID to a random ID. This only works in combination with --root=. On success, 0 is returned, a non-zero failure code otherwise. systemd.firstboot= Takes a boolean argument, defaults to on. If off, systemd-firstboot.service won't interactively query the user for basic settings at first boot, even if those settings are not initialized yet. systemd1, locale.conf5, vconsole.conf5, localtime5, hostname5, machine-id5, shadow5, systemd-machine-id-setup1, localectl1, timedatectl1, hostnamectl1
