I'm not sure Epoch is still being maintained, but when I used it it was
an outstanding init system. I wrote about it here:

http://www.troubleshooters.com/linux/init/manjaro_experiments.htm#pure_epoch_init_system

and here

First, it's pure, 100% serial instantiation[1]. No "parallel"
instantiation, so things like process prerequisites are handled simply
by the ordering of the "objects" (like systemd unit files) within the
config file. You might think serial instantiation would be slow, but
that wasn't my experience. Epoch booted faster than runit or sysvinit.
I was able to set up systemd to boot faster, but it took some doing,and
do systemd wrong and it makes sysvinit look supersonic.

Epoch is easy for anyone to understand, and is configurable by a user
with a minimum of muss and fuss.

[1] Epoch has a FORK ObjectOption that appears to be able to run a
    given service concurrently with the rest of the init process. Might
    be handy for stuff expected to take a long time.

I've used runit for 4 years and am used to it and love it, but for
certain simple setups, Epoch is wonderful.
