systemd-firstboot, systemd-firstboot.service — Initialize basic system settings on or before the first boot-up of a system
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:
The system locale, more
specifically the two locale variables
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 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.
The following options are understood:
Takes a directory path
as an argument. All paths will be
prefixed with the given alternate
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
settings. The argument should be a
valid locale identifier, such as
Sets the system time
zone. The argument should be a valid
time zone identifier, such as
Sets the system hostname. The argument should be a host name, compatible with DNS. This controls the hostname(5) configuration file.
Sets the system's machine ID. This controls the machine-id(5) file.
Sets the password of
the system's root user. This creates a
file. This setting exists in two
accepts the password to set directly
on the command line,
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
On success, 0 is returned, a non-zero failure code otherwise.
