There was a talk on January 08, 2014 at linux.conf.au Linux conference by Marc Merlin, Google server sysadmin and software engineer.
Quoting the description [1]: > This talk will look at how we upgraded our ancient linux distribution on all > the Google production > servers to a more modern one based on debian stripped down and built from > source. In his talk [2] at 13:50 Marc briefly touched the init system choice question. Perhaps it's worth taking into account.
