Open Stack

Hi!  Long time Linux admin, who's finally decided that the cloud is 
real, and I'm just thankful that there's an OSS answer to AWS.  And now, 
it's time to get my feet wet.  Which leads me to two questions:

1) I'm really surprised by how few books I see on OpenStack -- 
especially at the introductory level -- and how tepid the reviews for 
the O'Reilly books are.  Is there favored documentation, either dead 
tree, or electronic, that I should be checking out?

2) I'd really like to set up a home install -- DevStack seems to be the 
way to fly since I don't exactly have a rack of systems lying around for 
my own personal use.  Is there a better approach I should be taking?

Thanks much,

-Ken
