I'll fix 1. & 2. ASAP.
With the unsolved problem I must say that the OpenACS installer assumes people is using daemontools so when the installer shutdown the server it will come up automatically (which is a function of daemontools). In the debian dotlrn package we don't use daemontools so I'll modify the installer to reflect the fact that people must manually start the server again.
/etc/init.d/aolserver4 is the init script from the aolserver4 package and may collide with the dotlrn one, I'll figure out a solution or warn the user about it.
I'll post a revised version today, thank you for the support.
