Ask HN: What do you want to see in a deployment management system?

Deployment management can be a painful, slow and repetitive task if overlooked. There are tools available to ease our suffering: chef, cfengine, puppet, capistrano. While these can help, at times they feel like monstrosities to overcome in themselves. I use chef to deploy/maintain and apps and configs on <100 servers. The initial installation and learning curve was not as smooth as I'd have liked but now its doing a good job. Even still, I feel its lacking in some ways for my needs and the amount of moving parts required to keep it running frustrates me at times. In an ideal deployment management tool, what would you like to see? Is it ease of installation? A hosted solution? I'm looking to write something to simplify the process greatly not only for my own benefit but for others out there as well. I would like some insight into what your needs are or what you think a good deployment tool should be capable of. Thanks HN
