Trying to get a init.d/puma to work on Centos 6. It throws error

runuser: user /var/log/puma.log does not exist

I run this from the /srv/books/current folder but it fails. I tried to debug the values but not quite get what is missing and why it throws this error.

# It was modified here by Stanislaw Pankevich <[email protected]>
# to run on CentOS 5.5 boxes.
# Script works perfectly on CentOS 5: script uses its native daemon().
# Puma is being stopped/restarted by sending signals, control app is not used.
