Yes. I have a suggestion. I suggest we just start assembling a group of
Epoch object descriptions for the top 30 most used daemons. Then, as
people request them of other daemons, we add those. I suggest we keep
these as a group of scripts, *not* as anything the "upstream" has to
worry about.

Look how this works: In 3 weeks we can have 30 Epoch daemon object
recipes. sshd, ntpd, crond, httpd, all the usual suspects. In 3 weeks
we've satisfied 80% of the people, with no "help" from the "upstreams".
We let people know that if they need an Epoch object description for a
given daemon we don't yet support, we'll treat that like a bug report
and make such a Epoch object description. As time goes on we'll have a
big library of these things, and people will notice that Epoch object
descriptions are an order of magnitude easier to understand, and
therefore to DIY, as sysvinit scripts. Probably easier than systemd
unit files too, given that I've never heard any person describe how
systemd actually works.

You can have most of your easy Epoch installation, on Devuan, in 3
weeks. I have virtual machines, so I can help. It will be fun. And you
know what? I might just take each of those Epoch object descriptions,
and make a daemontools/daemontools-encore/runit/s6 run file based on it.
