There is usually no need to install Zope/ZEO as root.
It is "best practice" to install Zope/ZEO as unprivileged user.

Create a default install of Zope.
Run bin/mkzeoinstance.py to create a ZEO instance (as root).
Chown -R all files in the ZEO instance directory to be owned by 'zope'.
edit $INSTANCE/etc/zeo.conf and uncomment the '# user zope' directive.
Attempt to start zeo as the root user. Parent process will spin and child processes will die silently.

The problem is that the logfile ($INSTANCE/log/zeo.log) is created on the first run by the parent process, and is therefore owned by root. The child processes attempt to open the file for writing and get unhandled exception IOErrror Permission Denied (see traceback below).

Therefore, the parent process needs to create the logfile as the 'zope' user (or whatever is defined in zeo.conf).
