How can I modify init script to make it start after delay or event?

Question

I use supervisor.
I have configuration file that launches a task in a directory that is mounted after some time after system startup (/vagrant/task.sh).

So when system starts, supervisor can't start. I have to run sudo service supervisor start command after the system is loaded and the /vagrant directory is mounted.

How can I add delay to /etc/init.d/supervisor to make it start after delay or event?

Answer 1

I found out a solution (event vagrant-mounted):

cat << EOF > /etc/init/supervisor-launcher.conf
description "Supervisor Launcher"
start on vagrant-mounted
script
  /usr/sbin/service supervisor start
end script
EOF
