It's zdctl, which I never understood. It makes little monoliths of zdaemon
and programs in undocumented (AFAICT) and brittle ways.

I really like zdaemon, because it only does one simple thing. And I always
configure it simply as described in it's documentation, generally using
zc.zdaemonrecipe, https://pypi.python.org/pypi/zc.zdaemonrecipe.  I don't
try to combine the configuration of zdaemon and ZEO.

(I happen to prefer zdaemon over supervisord, because it lets me think
about different processes separately, and because it's simpler.)

OK, looking at:

https://pypi.python.org/pypi/plone.recipe.zeoserver

I created a buildout config:

[buildout]
parts = zeo

[zeo]
recipe = plone.recipe.zeoserver
zeo-address = 8100

When I run it, I get:

...
While:
  Installing zeo.

An internal error occurred due to a bug in either zc.buildout or in a
recipe being used:
Traceback (most recent call last):

whimper.

Any idea what extra magic I'm missing?

If I had a working example of zeoctl, I could double check my fix, but I'm
tempted to just release a possible fix and see if Plone gets better.
