systemd-vconsole-setup.service, systemd-vconsole-setup — Configure the virtual consoles
systemd-vconsole-setup is a helper used to prepare either all virtual consoles, or — if the optional TTY parameter is provided — a specific one. When the system is booting up it's called by systemd-udevd(8) during vtconsole subsystem initialization. Systemd(TM) also calls it internally as needed via systemd-vconsole-setup.service. The helper calls loadkeys(1) and setfont(8) internally.
You may want to use this helper whenever you change vconsole.conf to refresh the settings on your consoles — either through the systemctl restart / systemctl start command or directly through the executable.
See vconsole.conf(5) for information about the configuration files and kernel command line options understood by this program.
