You could try to run the Alfresco init script backgrounded
(/etc/init.d/alfresco start &) or even nohup'ed (nohup
/etc/init.d/alfresco.start > /var/log/alfresco-restart.out 2>&1 &) and
see if that at least lets Bacula continue.
I assume the init script somehow hangs, for example if it doesn't have
a terminal. But that's something to debug separately...
