Correction: the *s6_service_path* parameter in the parent init.d service,
/etc/init.d/container, needs to be changed from
/run/openrc/s6-scan/${INSTANCE} to /var/svc.d/${INSTANCE}
*#!/sbin/openrc-rundescription="A supervised test service with a
logger"supervisor=s6**s6_service_path=/var/svc.d/${INSTANCE}*
*depend() {*
* need s6-svscan*
*}*
*stop_pre() {*
* docker stop ${INSTANCE}*
*}*
NB; In runlevels, dont need to include s6-svscan. Only need to include the
service to start (s6-svscan will start as a service dependency).
Further info (go from runlevel 90 > 100 > back to 90):
root@/etc/runlevels #
* ls -ld node/*lrwxrwxrwx 1 root root 24 May 25 06:17 100/container.whoami
