Speaking in my capacity as a downstream consumer, I would much prefer
upstream to carry scripts for each init system.

IMO, the benefits of not repeatedly solving the same bug different ways,
and a wider set of eyes checking changes outweigh the problems of things
getting out of sync.

Testing can be trivially gated by running OSS test on different base
distros and strictly not using sysvinit compatibility.

And speaking of upstart, XenServer has some experimental upstart
configuration files for use in a CentOS 6.x environment.  (They should
be on github, but it would appear github is out of date, which I need to
