SYSTEMD-FIRSTBOOT(1) systemd-firstboot SYSTEMD-FIRSTBOOT(1)
NAME
systemd-firstboot, systemd-firstboot.service - Initialize basic system settings on or
before the first boot-up of a system
SYNOPSIS
systemd-firstboot [OPTIONS...]
systemd-firstboot.service
DESCRIPTION
systemd-firstboot initializes the most basic system settings interactively on the first
boot, or optionally non-interactively when a system image is created. The following
settings may be set up:
o The system locale, more specifically the two locale variables LANG= and LC_MESSAGES
o The system time zone
o The system host name
o The machine ID of the system
o The root user's password
Each of the fields may either be queried interactively from the 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 localectl(1), timedatectl(1) or hostnamectl(1). 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.
OPTIONS
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.conf(5) 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 localtime(5) symlink.
--hostname=HOSTNAME
Sets the system hostname. The argument should be a host name, compatible with DNS.
This controls the hostname(5) configuration file.
--machine-id=ID
Sets the system's machine ID. This controls the machine-id(5) file.
--root-password=PASSWORD, --root-password-file=PATH
Sets the password of the system's root user. This creates a shadow(5) file. This
setting exists in two forms: --root-password= accepts the password to set directly on
the command line, --root-password-file= reads it from a file. Note that it is not
recommended specifying passwords on the command line as other users might be able to
see them simply by invoking ps(1).
--prompt-locale, --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, timezone, hostname and root password. This is equivalent to
specifying --prompt-locale, --prompt-timezone, --prompt-hostname,
--prompt-root-password in combination.
--copy-locale, --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, time zone and root password from the host. This is equivalent to
specifying --copy-locale, --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=.
-h, --help
Print a short help text and exit.
--version
Print a short version string and exit.
EXIT STATUS
On success, 0 is returned, a non-zero failure code otherwise.
