Effective user issue with zope

[Madhusudan Singh]

Hi

 I am setting up zope-2.7.5-final on a server (FreeBSD 5.3-RELEASE).
Installed python-2.3.5 from sources (not ports). After configuring and
compiling it correctly, I got an initial error on running runzope.
Following the exhortation I found on the following webpage :

http://mail.zope.org/pipermail/zope/2004-May/149695.html

 I created a new user (zopeuser), added it to group users, and tried to run
runzope as that user. I also changed the effective_user to zopeuser in
zope.conf. However, I now get the error :

 Traceback (most recent call last):
  File "/usr/local/zope/lib/python/Zope/Startup/run.py", line 50, in ?

    self._fp = open(path, 'w+')
IOError: [Errno 13] Permission denied:

 I understand partially why this error is occuring - zopeuser does not have
write permissions in the instance directory. I wonder how is this issue
resolved - does one change the group ownership of the entire zope tree to a
new group (say zopeusers) and add zopeuser to that group, or what ?

Thanks.
