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.unit(5) for details.
The following settings may be set up:
· The system locale, more specifically the two locale variables
LANG= and LC_MESSAGES
· 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 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.
The following options are understood:
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.
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.
Sets the system time zone. The argument should be a valid time
zone identifier, such as "Europe/Berlin". This controls the
Sets the system hostname. The argument should be a host name,
compatible with DNS. This controls the hostname(5) configuration
Sets the system's machine ID. This controls the machine-id(5)
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, 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
--prompt-locale, --prompt-timezone, --prompt-hostname,
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.
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
--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 locale, time zone and root password from the host. This is
equivalent to specifying --copy-locale, --copy-timezone,
--copy-root-password in combination.
Initialize the system's machine ID to a random ID. This only
works in combination with --root=.
Print a short help text and exit.
Print a short version string and exit.
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
