[Zope] Cannot pack Data.fs, Permission Denied error

[Chris McDonough]

Hi John,

Change the permissions of the var dir and all of its its contents to be
writable by the -u user.  Then start Zope as root with the -u switch. 
That should solve the problem.

This problem is a symptom of the way Zope 2.6 and prior handle UNIX
setuid wrt log files and database files.  Zope 2.7 handles it
differently and does not have this problem.
