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_MESSAGESThe system time zoneThe system host nameThe machine ID of the systemThe root user's passwordEach 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.OptionsThe 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.conf5
configuration file.Sets the system time zone. The argument should
be a valid time zone identifier, such as
Europe/Berlin. This controls the
localtime5
symlink.Sets the system hostname. The argument should
be a host name, compatible with DNS. This controls the
hostname5
configuration file.Sets the system's machine ID. This controls
the
machine-id5
file.Sets the password of the system's root user.
This creates a
shadow5
file. This setting exists in two forms:
accepts the password to set
directly on the command line, and
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 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
,
,
,
in combination.Copy a specific basic setting from the host.
This only works in combination with
(see above).Copy locale, time zone and root password from
the host. This is equivalent to specifying
,
,
in combination.Initialize the system's machine ID to a random
ID. This only works in combination with
.Exit statusOn success, 0 is returned, a non-zero failure code
otherwise.Kernel Command Linesystemd.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.See Alsosystemd1,
