Hi there,

I'm trying to setup a "discless" ZEO client. The INSTANCE_HOME is
pointing to '/var/run/zope'[1] (/var is mounted on a ramdisk).
If I try to start zope with=20
`/usr/sbin/zopectl -I /var/run/zope/ start -P 8000 -u www-data -D`
I get the errors in [2]. The custom_zodb.py looks like [3]. Afaik all
file permissions/modes are set correctly, what else might be the reason?
ZEO is running smooth, everything works if I try to run Zope with a
default INSTANCE_HOME. If I remove the old INSTANCE_HOME and supply a
custom one I get those erros in [1]...

some more info:
Zope version: 2.5.1-1 (from debian woody)
python version: 2.1.3


Thnx in advance,
Igor
