You can retrieve the values by checking what debconf has set, but if you've also modified things manually, then it might not be accurate anymore. > (2) Is it possible to run the installer from the CD in automatic mode > (i.e. without any human support), just configuring some linux boot > option?

You can follow documentation that is already defined for "preseeding" installations: https://help.ubuntu.com/lts/installation-guide/amd64/apbs02.html This document focuses on the use of preseed in debian-installer, which is slightly different than ubiquity. The main differences are that rather than using "auto", you'll want to use "automatic-ubiquity", and some debconf keys are different. As an example, I have an old preseed that should still work: http://people.canonical.com/~mtrudel/preseed/full.cfg This would run through a very standard installation, putting everything in / (not separating into multiple partitions). The lines that are commented out are examples for other uses, and don't apply for this standard install. There is also: http://people.canonical.com/~mtrudel/preseed/crypto.cfg Which is an example of a preseed that sets up full-disk encryption and only stops to ask the user to enter the encryption passphrase. It also contains an example for a ubiquity/success_command, which would allow you to create extra users. The details as to what each line does are in the document linked earlier. > (3) it is possible to tell Ubiquity *not* to umount the future "root" > partition? > You likely *do* want it to be unmounted normally. If you do any final "manual" setup of the install as a success_command, then it will still be available for you when that script runs. / Matt
