as explained in h2o/h2o#84 (comment) the init script for sysvinit doe snot work cos does nohting for stop and restart commands:

root@debian:/etc/h2o# service h2o status
[ ok ] h2o is running.
root@debian:/etc/h2o# service h2o stop
root@debian:/etc/h2o# service h2o status
[ ok ] h2o is running.

This problem is not well detected in debian recent shit versions cos are infgected by shistemd process but in MXlinux and devuan fails cos shistemd process are not used and init script is well used!

i will put a PR to fix the script @hsbt @tatsushid
