Try posting again with a different subject line: Is there a way to safely bypass apt's pre-inst scripts? or something like that. It sometimes works for me. sebyte P.S.

I'm not sure how it'll interact with conffile replacement prompts however.

The pages I have read talk only of a 'yes to all questions' option which is obviously useless if the package you are installing has questions other than yes/no and so on. The docs also speak of being able to set *arbitrary* options in the command line. This seemed to be more related to the apt-get program rather than the packages. Two examples I want to do are Apache2 and PostgreSQL which require some additional prompting. The purpose here is to create a set of steps which can quickly install a Debian system from scratch, limit down-time and remove some of the human element. Is there a way of doing this? I'm at about a 3 bananas out of 5 on the howler monkey scale. How about debconf pre-seeding? Most programs use debconf to ask the questions. However if debconf already has answers to the questions then it does not bother to ask them. In fact the config script is apparently sometimes run in both the pre-inst and the postinst so ignoring questions which have answers already is almost critcal. The following is one way to pre-seed debconf. With this method it is very important that you not pre-seed for any packages that will not be installed, because otherwise those values will rot in the database forever. Anyway lets say the package name is 'foobar' From a system where it is already configured you should run: debconf-get-selections|grep ^foobar > foobar.preseed Then to load that into the database to avoid the questions, simply get the file onto the system and run: debconf-get-selections foobar.preseed Note thatyou can concatonate a bunch of these file together if you want. This will then let you use only one line to pre-seed a whole bunch of packages. There are also other ways to pre-seed, but I don't know about them. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]

This could be dangerous, as some packages generate additional files and whatnot during post-inst. The information gathered during pre-inst is usually relevant there. I am not sure if they all have sane defaults in the absence of the pre-inst input. -Roberto -- No virus found in this outgoing message. Checked by AVG Free Edition.

It's during the execution of these scripts that most of these questions are asked for the purposes of creating config files. If you can put the config files in place by some other method you might be able to automate the install by bypassing the pre-inst scripts. I'm only guessing mind you, but it might be an angle to explore. sebyte -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
