[chiglug] systemd

[Rob Dux]

I'd like to know where systemd shines i.e. what is the best application for
systemd and my current belief is desktop. I interact with it in fedora and
when I have to shell into servers that use it.

We're adopting Docker at my employer for which I gave a talk last lug and
there is a requirement for an init system in some applications for
containers which I selected s6 for various reasons. As far as Docker hosts,
Alpine Linux seems most ideal and it ships with OpenRC. In every case for
our production needs, minimalism is the key. Microservices are the trend
now and on the horizon is unikernels where init is irrelevant.
