Остановка фальшивой службы / демона в Ubuntu 16.04

Поскольку самый разумный ответ уже был дан, вот безумный - используйте эту файловую систему:

Таким образом, ваша программа не заметит, что разговаривает с конвейером.

Я написал сервис LSB для Ubuntu 16.04, проблем не возникло:

# lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 16.04.4 LTS
Release:    16.04
Codename:   xenial

Добавление новой службы fake-serviceв /etc/init.dс разрешениями 755:

#!/bin/sh
# fake-service   Bring up/down fake-service
#
### BEGIN INIT INFO
# Provides:     fake-service
# Default-Start:    2 3 4 5
# Default-Stop:
#Required-Start:
#Required-Stop:
# Should-Start:
# Should-Start:
# Short-Description: Bring up/down fake-service
# Description: Bring up/down fake service
### END INIT INFO

DAEMON=
NAME=fake-service
DESC="fake-service"
PIDFILE=/var/run/fake-service.pid
SCRIPTNAME=/etc/init.d/fake-service

. /lib/lsb/init-functions

case "$1" in
start)
    log_daemon_msg "Starting fake-service..." "$NAME"
    touch $PIDFILE
    log_end_msg $?
;;
stop)
    log_daemon_msg "Stoping fake-service..." "$NAME"
    rm -f $PIDFILE
    log_end_msg $?
;;
status)
    status_of_proc -p $PIDFILE $DAEMON $NAME && exit 0 || exit $?
;;
*)
    log_action_msg "Usage: $0 {start|stop|status}"
    exit 2
    ;;
esac

exit 0

Добавление его в уровни прогона -:

# update-rc.d fake-service defaults

Изman 8 update-rc.d:

When run with the defaults option, update-rc.d makes links named /etc/rcrunlevel.d/[SK]NNname that point to the script /etc/init.d/name, using runlevel and dependency information from the init.d script LSB comment header.

Служба тестирования:

Запуск:

# service fake-service start
# service fake-service status
