After adding a few LSB headers into the init.d installed in my test
chroot, I wanted a script to check if the ordering was correct. Here
is a script to do that. It is just a prototype, and should be
improved a lot, but I wanted to share it with the rest of you to
provide you all with the tools I have at the moment.
It is useful to check the result generated by insserv.
