Comment 3 for bug 441141

I think the problem is burried in ZEO/mkzeoinst where the 'zdrun' path is hard-coded
and does not reflect the reality (zdaemon is not part of the ZODB package). I think
that mkzeoinst should detect the path of the zdaemon package and use its path
instead

65 <runner>
 66 program $INSTANCE/bin/runzeo
 67 socket-name $INSTANCE/etc/%(package)s.zdsock
 68 daemon true
 69 forever false
 70 backoff-limit 10
 71 exit-codes 0, 2
 72 directory $INSTANCE
 73 default-to-interactive true
 74 # user zope
 75 python %(python)s
 76 zdrun %(zodb3_home)s/zdaemon/zdrun.py
 77
 78 # This logfile should match the one in the %(package)s.conf file.
 79 # It is used by zdctl's logtail command, zdrun/zdctl doesn't write it.
 80 logfile $INSTANCE/log/%(package)s.log
 81 </runner>
