### run packstack multiple time.

Hello,

This may be a basic thing, But May I ask a question in this forum?

I have installed all component of grizzly except swift by following packstack command.

"packstack --gen-answer-file=ANSWER_FILE"


Additionally I would like to add swift to modify the answer file. because the parametor of swift is NO in default.

# diff packstack-answer-OLD.txt packstack-answer-NEW.txt
19c19
< CONFIG_SWIFT_INSTALL=n
---
> CONFIG_SWIFT_INSTALL=y


In case of this, if run packstack again,

"packstack --gen-answer-file=packstack-answer-NEW.txt"


Does it change something of existing environment (Keystone,Nova,Quantum...etc)? Is it just only additional installation of swift without affecting other existing components?

Basically if run packstack multiple time, Does the only modified portion of answer file apply at every time?

thank you.
