Welche Werte aus debconf-get-selections sollten nicht vorgegeben werden?

8

Ich möchte die Debian-Installationsoptionen replizieren, die für die aktuelle Konfiguration meines Systems bei der Installation eines neuen Systems getroffen wurden.

Debian kann über eine "Vorkonfigurations" -Datei (auch als "Voreinstellung" bezeichnet) vorkonfiguriert werden, die im Wesentlichen die Antworten auf die Fragen enthält, die das Installationsprogramm stellen wird.

In der Dokumentation heißt es, dass eine Möglichkeit zum Erstellen einer Vorkonfigurationsdatei aus einer vorhandenen Installation von Debian darin besteht, Folgendes zu tun:

... verwenden Sie das debconf-get-selectionsPaket aus dem debconf-utils-Paket, um sowohl die debconf-Datenbank als auch die cdebconf-Datenbank des Installationsprogramms in einer einzigen Datei abzulegen:

$ debconf-get-selections --installer > file
$ debconf-get-selections >> file

Aber es fügt dann sofort hinzu:

Eine auf diese Weise generierte Datei enthält jedoch einige Elemente, die nicht vorab festgelegt werden sollten ...

In der Dokumentation wird nicht näher erläutert, um welche Elemente es sich handelt, die nicht vorab festgelegt werden sollten.

Könnte jemand näher darauf eingehen?


Zur Veranschaulichung füge ich unten das zweite Feld der Ausgabe ein, das ich von den beiden obigen Befehlen erhalte, wobei ich nur die Zeilen, die mit beginnen d-i, zusammen mit den Kommentaren beibehalten habe, die der Kürze halber manchmal abgeschnitten sind. (Der Grund dafür, dass nur die Konfigurationszeilen beibehalten werden, die damit beginnen, d-iist, dass in der von Debian bereitgestellten Beispielvorkonfigurationsdatei nur solche Zeilen angezeigt werden.)

Kurze Antwort

Von der Debian-Wiki-Seite, die DI preseed gewidmet ist :

Arbeiten Sie nicht eine von debconf-get-selections (--installer) generierte preseed.cfg ab, sondern holen Sie die Werte daraus und ändern Sie die Beispiel-preseed-Datei mit ihnen.

Die von Debian bereitgestellte Preseed- Beispieldatei sollte zum Starten ausreichen, aber Sie können viele andere Preseed-Dateien, die von verschiedenen Personen für verschiedene Zwecke bereitgestellt wurden, auf derselben Wiki-Seite finden.

Weniger kurze Antwort

In der Liste der von Ihnen geposteten Debconf-Fragen sollte nicht jede Frage mit einem Kommentar "für den internen Gebrauch" ohne "kann vorab festgelegt werden" vorab festgelegt werden.

Viele andere Debconf-Fragen können jedoch möglicherweise nicht mit einer vorab festgelegten Datei vorab beantwortet werden, z. B. die hardwarebezogenen Fragen (wenn Sie die Installation auf einer anderen Hardware ausführen möchten) und die Fragen, die einen automatischen Konfigurationsfehler oder -erfolg aufzeichnen (was möglich ist) in einigen besonderen Fällen vorab festgelegt werden, aber ohne Probleme mit dem automatischen Prozess beantwortet werden können).

Die Ausgabe von debconf-get-selections enthält viele automatisch beantwortete Fragen, die die meisten Menschen nie sehen und die sie nicht interessieren (sollten). Diese automatische Auswahl ändert sich im Laufe der Zeit mit neuer Hardware, Software, besserer Erkennung oder neuen Möglichkeiten. Es ist wichtig, die automatische Konfiguration so wenig wie möglich zu berühren, um von allen Verbesserungen des Debian-Installationsprogramms zu profitieren und die erforderlichen Änderungen an Ihrer vorab festgelegten Datei im Laufe der Zeit und für unterschiedliche Hardware auf ein Minimum zu beschränken.
