Hi Aldert,
I use the install.sh script in the darwinports install and I had the same problem. I changed the start_server_command variable in install.tcl.
-set start_server_command "exec /usr/local/aolserver/bin/nsd-postgres -it $serverroot/etc/config.tcl -u $aolserver_user -g $aolserver_group"
+set start_server_command "${aolserver_home}/bin/nsd-postgres -t ${serverroot}/etc/config.tcl -u $aolserver_user -g $aolserver_group &"
It works now with daemontools set to false, but I haven't tested if it messes up the daemontools install.
