[chef] best ticketing system for Chef

[哲 曹 < >]

Hi,

I am using Bugzilla to manage system management request.
However, bugzilla does not good at customizable work flow.
And I find it difficult to integrate it with Chef to process request 
automatically.

Jira, Trac and so many ticketing/bug tracking systems are designed for 
software development but not for system operations.

So, any suggestion on ticketing for system operations/infrastructure 
management ?

Thank you!
