Webserver configuration, virtualization

For system administrators, elementary arguments for setting a complex Rails production environment would be passenger installation, configuration and tuning (and say nginx and unicorn for completeness), as well as system permissions, dev libraries needed on base system, maintenance of gems through deployment bundles, “static” ‘database.yml’s handling, Rails Enterprise RVM etc., all topics I can’t see in the book up to now.
Further, Puppet is a great tool, but is this a book about Puppet or about setting Rails production servers?

Finally, Vagrant may be cool, but VirtualBox has a reputation of being a toy in certain business.

This is my thought :)

Yup, the first few chapters in the book are pretty Puppet/Vagrant-heavy. There’ll be more content in the next beta release that will contain more Rails server-related stuff. So, something to look forward to…

What about inserting a Chapter 2 explaining general server configurations (Passenger, database, users handling (chrooted homes?), permissions etc.) before the chapters on Vagrant and Puppet?

Just to close the loop on this, I think we’re handling this pretty well in the Puppet chapter now.
