# Set the true hostname.
#
# systemd has already set the hostname when this unit executes (based on
# the original /etc/hostname).
#
# However, since that file is on the read-only rootfs and the real
# hostname is on the writable partition (/etc/writable bind-mount), it
# is necessary to reset the hostname as soon as the true hostname file
# is available.
