Ideas for future development: https:/
* two main features worked on this cycle
* refining ptrace handling for upstart for service readiness
* cgroup support
* nice-to-haves:
* time bridge
* upstart user sessions on terminal logins
= cgroup support =
* cgroup manager should be started early in boot
* apw points out that it could be started directly from upstart before any job parsing (treating it as internal to upstart); this is an option but probably not necessary
* deal gracefully with the kernel not having cgroup support
* cgroup support needs to be both a build-time and runtime option; if enabled, missing cgroups should be fatal for the job
* if cgroups are not disabled, jobs specifying the 'cgroup' stanza will block until the cgroup manager has started.
* cgroups should be applied to all job processes (pre-start, exec, etc)
* document carefully.
* should we support the case where multiple job instances share the same group?
possible syntax: 'cgroup <controller> <cgroup-name|auto> [key=value]'
* we want cgroup support for user jobs
* one cgroup per user per controller
