Understood. I have much to do, also.
So far from the MiniMe draklive-install file, I have found this:
Lines 344 to 349 -
require services;
services::start_service_on_boot("dkms");
services::start_service_on_boot("anacron");
services::start_service_on_boot("atd");
services::start_service_on_boot("crond");
services::start_service_on_boot("syslog");
This would be the "# enable back some disabled services" part.
Line 306 -
system("chroot $in->{prefix} touch /etc/delete-guest-account");
For keeping the guest account.
For "# Setup for root password and create new user at 1st boot" I'm going to do a bit more investigating. But I think it is lines 391 to 400 that need to be commented. I'm not certain of this, so it will probably be better to wait to see what more can be learned.
There's another file, Install-Interactive, that bears some investigation.
