Executing a script on shutdown-restart, what's wrong?

Question

linux

Ubuntu 15.10
For some reason, the script is not executed on restart or shutdown. Actually the whole process
For the test, I wrote the following script finish-yandex.sh:

#!/bin/sh
### BEGIN INIT INFO
# Provides:          finish-yandex
# Required-Start:
# Required-Stop:
# Default-Start:
# Default-Stop:	     0 1 6
# Short-Description:  Save yandex config.
# Description:
### END INIT INFO
echo "it works test" >> /home/user/.yandex_ram/test.log

I add the file finish-yandex.shto the folder /etc/init.d/and make it executable.
sudo chmod +x /etc/init.d/finish-yandex.sh
Next, I execute the command
sudo update-rc.d finish-yandex.sh stop 01 0 1 6 .
. A message appears:

update-rc.d: warning: start and stop actions are no longer supported; falling back to defaults

/etc/rc0.d/ /etc/rc1.d/ /etc/rc6.d/Symlinks appear in the folders . K01finish-yandex.sh
After I reboot and there is a bubble, test.logthere is no folder in the folder ...
I tried to manually make symlinks in /etc/rc0.d/ /etc/rc1.d/ /etc/rc6.d/with the name K00finish-yandex.shor S00finish-yandex.shand it does not work.
What's wrong? Why does not it work?
Thank you.
UPD: Everything written above is most likely suitable for Ubuntu 14.10 and below (did not check)

From here

How can I make the script run when the machine is turned off? The /etc/rc6.d directory contains scripts that are executed when the machine is rebooted. The /etc/rc0.d directory contains scripts that are executed when the machine is turned off. I put a symbolic link in the /etc/rc0.d directory, because I need the script to be executed when the computer is turned off. Named the file S00backup. And all business. Everything turns off and backs up as it should.

Answer 1

Solution for Ubuntu 15.10 (I think it works on 15.04 and above too):
Don't forget to change user to your own Let's
create a new file, I called it finish-yandex, with the following content:

[Unit]
Description=Save Yandex config
After=systemd-user-sessions.service

[Service]
ExecStop=/bin/bash '/home/user/.yandex_ram/finish-yandex.sh'
Type=oneshot
RemainAfterExit=yes

[Install]
WantedBy=multi-user.target reboot.target poweroff.target

A little about the file

Unit - общая информация.
Description - описание сервиса.
After - задаёт порядок загрузки. В моём случае после старта сессии пользователя.

Service - содержит информацию о службе
ExecStop - Выполняет команду при остановке сервиса.
Type - Типы службы. oneshot полезен для скриптов, которые выполняют одно задание и завершаются

Install - когда юнит должен быть активирован

finish-yandex.sh for the test contains:

#!/bin/sh
echo "it works test" >> /home/user/.yandex_ram/test.log

Make the finish-yandex file executable:
Copy the file to /etc/systemd/system with *.service extension:
Reload systemd to search for new or changed units:
Enable the unit to autostart on system boot:
Reboot and check. Everything worked for me, the test.log file appeared after the reboot.
To check for a start without a reboot, you can start and stop the unit:

sudo systemctl start finish-yandex.service

sudo systemctl stop finish-yandex.service

To disable a unit from autorun on system boot:

Try to use full path to echo
For example:
/bin/echo
