Checking if nginx is running using and a mixture of file tests and `pidof` is fragile. Debian policy 9.3.3 states that `invoke-rc.d` should be used instead to perform these checks. In addition, the use of `pidof` creates an implicit depency on `sysvinit-utils`. `sysvinit-utils` is currently essential, but that may change in the future.
