> base docker VM

you serious? criticizing systemd by promoting a totally new and un-tested software written by a single (for-profit) company.

> Also a lot of enterprise shops use daemontools and runit

provably not true. most enterprise shops run RHEL/CentOS which, to keep support contracts, runs sysvinit or in RHEL/CentOS 6.x ran Upstart. RHEL/CentOS 7 uses systemd and is not going to look back. Don't forget, the "serious" distros have used sysvinit for a very long time. Then they tried out Canonical's Upstart for a bit and decided it was not a step forward, but rather a step to the side. Now they have landed on systemd for very good reasons.

No, sorry, but you don't know what you're talking about.

daemontools is battled tested. We used it at Stanford on thousands of boxes. I used at a lot of shops, one in SF for example had 40k boxes (CentOS) and 6 ops staff, deployed via CFEngine. Heroku uses daemontools. On and on. Daemontools is mostly used when there is no desire/time to replace the existing init completely.

runit also scales amazingly well, even though it's more work to deploy.

Upstart is too unpredictable (flapping) and sysvinit doesn't do supervising very well, which is why important services are deployed with daemontools/runit.
