[chef] knife ec2 - knife.rb takes precedence over command line options

[Nick Peirson < >]

Hi All,

Is this the expected behaviour? I've raised it as an issue in github 
(https://github.com/opscode/knife-ec2/issues/41), but thought I'd seek 
others opinions here as well. It seems to prevent knife ec2 commands 
from being scripted effectively if there are entries in knife.rb.

Use case is having defaults in knife.rb to spin up instances quickly 
while testing things without having to type a command line as long as 
your arm, but occasionally want a different AMI or to start an instance 
in a different AZ by quickly overriding on the command line. At the 
moment it's a case of having to change the knife.rb, run the command, 
change it back or, alternatively, leave the options out of knife.rb and 
always pass as command line arguments.

It surprises me that this isn't affecting anyone else, so I'm wondering 
if I'm doing something to cause this behaviour?

Cheers
Nick
