Hi Nils, rc_sys from /etc/rc.conf is empty, but after removing -lxc from /etc/init.d/hostname the service is well started. Thanks!
So, for the record:
as112 ~ # grep rc_sys /etc/rc.conf
#rc_sys=""
as112 ~ # grep keyword /etc/init.d/hostname
keyword -docker -lxc -prefix -systemd-nspawn
as112 ~ # vim /etc/init.d/hostname
as112 ~ # rc-status boot | grep hostname
hostname [ started ]
as112 ~ # grep keyword /etc/init.d/hostname
keyword -docker -prefix -systemd-nspawn
as112 ~ #
Cheers,
