0.9 install: fatal: unable to acquire lock on/opt/api-umbrella/var/run/perpboot.pid: temporary i/o failure (EAGAIN)

After installing 0.9 and editing the api-umbrella.yml file, we get the following error when starting the service:

$ sudo service api-umbrella start
 * Starting API Umbrella api-umbrella
 runtool: fatal: unable to acquire lock on/opt/api-umbrella/var/run/perpboot.pid: temporary i/o failure (EAGAIN)

This may be resolved by using restart instead of start, but I have not tested this difference.

This message would show up if the service was already started and you ran the start command again. This is improved in 629dc34. Now if you run the start command when api umbrella is already started or the stop command when api umbrella is already stopped, you'll get a more instructive message. This will be part of v0.10 which will be released tomorrow.
