I feel like there is a huge upcoming market for well designed developer-centric tools that allow developers to use stuff like SELinux without also becoming a sysadmin. SELinux feels like a tool only a system admin could love. Puppet (or Chef, Ansible etc) feel like only a tool a release automation engineer could love.

Startups and small companies rarely spend enough on operations and I feel as if there is bit of a death by a thousand paper cuts across the board for productivity and security due to tools written for sysadmins, and "devops" engineers.
