Packing of ZODB requires temporary to change ownership of /var/lib/zope/zope-2_6_1/var from zope to root. However, the Zserver won't start if that folder belongs to zope rather than root. Reproducible: Always Steps to Reproduce: 1. go to ZMI 2. pack ZODB and see that it fails 3. chown zope /var/lib/zope/zope-2_6_1/var 4. pack ZODB again and see that it packs successfully now. 5. still in ZODB, restart the server (or from CLI) and see it doesn't restart. 6. chown root /var/lib/zope/zope-2_6_1/var 7. /etc/init.d/zope-2_6_1 restart and see that now it's restarted successfully Actual Results: As for now packing and restarting require different (and mutually exclusive!) ownership of /var/lib/zope/zope-2_6_1/var Expected Results: packing and restarting should work being called from inside ZMI without any twicking filesystem permission/ownership # emerge -pv zope These are the packages that I would merge, in order: Calculating dependencies ...done! [ebuild R ] net-zope/zope-2.6.1
fixed in dev-zope/zope-2.6.2
(just add zope to the zop_2_6_2 group)
