vconsole.conf — Configuration file for the virtual console
/etc/vconsole.conf
The /etc/vconsole.conf file
                configures the virtual console, i.e. keyboard mapping
                and console font. It is applied at boot by
                systemd-vconsole-setup.service(8).
The basic file format of the
                vconsole.conf is a
                newline-separated list of environment-like
                shell-compatible variable assignments. It is possible
                to source the configuration from shell scripts,
                however, beyond mere variable assignments no shell
                features are supported, allowing applications to read
                the file without implementing a shell compatible
                execution engine.
Note that the kernel command line options
                vconsole.keymap=,
                vconsole.keymap.toggle=,
                vconsole.font=,
                vconsole.font.map=,
                vconsole.font.unimap= may be used
                to override the console settings at boot.
Depending on the operating system other configuration files might be checked for configuration of the virtual console as well, however only as fallback.
The following options are understood:
KEYMAP=, KEYMAP_TOGGLE=¶Configures the key
                                mapping table for the
                                keyboard. KEYMAP=
                                defaults to us if
                                not set. The
                                KEYMAP_TOGGLE= can
                                be used to configure a second toggle
                                keymap and is by default
                                unset.
FONT=, FONT_MAP=, FONT_UNIMAP=¶Configures the console font, the console map and the unicode font map.
