Let's say you have a SysV Init Script named foo

Copy the file to /etc/init.d/foo
Enable the SysV service: chkconfig --add foo
Enable the SysV service: chkconfig foo on
Start the service: service foo start. After this, systemd-sysv-generator will generate this file /run/systemd/generator.late/foo.service, copy this file to /etc/systemd/system by running: cp /run/systemd/generator.late/foo.service /etc/systemd/system/foo.service
Edit /etc/systemd/system/foo.service by running systemctl edit foo.service, add in the following line to foo.servie (this makes the service installable)

[Install]

This script helps to clean up vmss nodes that may have Azure disks attached to it that should not be due to bugs in Kubernetes. The specific case for this is that a disk has been re-attached to by Kubernetes when it should not have been.

This DOES NOT detect a bad node/disk, only assists in cleaning it up.
