Nilai apa dari debconf-get-selection yang seharusnya tidak dipra-presed?

8

Saya ingin meniru pilihan instalasi Debian yang dibuat untuk konfigurasi sistem saya saat ini dalam pemasangan sistem baru.

Debian dapat dipra-konfigurasi melalui file "pra-konfigurasi" (alias "preseed"), yang pada dasarnya berisi jawaban atas pertanyaan yang akan diajukan oleh penginstal.

The dokumentasi menyatakan bahwa salah satu cara untuk membuat file preconfiguration dari instalasi yang sudah ada Debian adalah untuk:

... gunakan debconf-get-selectionsdari paket debconf-utils untuk membuang basis data debconf dan basis data cdebconf installer ke satu file:

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

Tetapi kemudian segera menambahkan:

Namun, file yang dihasilkan dengan cara ini akan memiliki beberapa item yang tidak boleh dilihat sebelumnya ...

Dokumentasi tidak menguraikan tentang apa barang-barang-yang-seharusnya-tidak-akan-prese akan menjadi.

Bisakah seseorang menguraikan?


Sebagai ilustrasi, di bawah ini saya memasukkan bidang kedua dari output yang saya dapatkan dari dua perintah di atas, di mana saya hanya menyimpan baris yang dimulai dengan d-i, bersama dengan komentar, kadang-kadang dipotong untuk singkatnya. (Alasan untuk menjaga hanya baris konfigurasi yang dimulai dengan itu d-iadalah dalam contoh file pra-konfigurasi yang disediakan oleh Debian, hanya baris tersebut yang muncul.)

Jawaban singkat

Dari halaman wiki Debian yang didedikasikan untuk DI preseed :

Jangan mematikan debconf-get-choices (--installer) yang dihasilkan preseed.cfg tetapi dapatkan nilainya dari itu dan modifikasi contoh file preseed dengannya.

The Preseed contoh file yang disediakan oleh Debian harus enought untuk memulai tetapi Anda dapat menemukan banyak file Preseed lain yang disediakan oleh orang yang berbeda untuk tujuan yang berbeda pada halaman wiki yang sama.

Jawabannya kurang singkat

Dalam daftar pertanyaan debconf yang Anda poskan, setiap pertanyaan dengan komentar "untuk penggunaan internal" tanpa "dapat dipra-teskan" tidak boleh dipra-prakan sebelumnya.

Tetapi banyak pertanyaan debconf lainnya mungkin tidak dijawab sebelumnya dengan file preseed, seperti pertanyaan yang terkait dengan perangkat keras (jika Anda ingin menjalankan instalasi pada perangkat keras yang berbeda), pertanyaan-pertanyaan tersebut mencatat beberapa kegagalan atau keberhasilan konfigurasi otomatis (yang dapat preseed dalam beberapa kasus khusus tetapi bisa tanpa masalah dijawab dengan proses otomatis).

Output dari debconf-get-selection berisi banyak pertanyaan yang dijawab secara otomatis yang kebanyakan orang tidak pernah lihat dan lakukan (seharusnya) tidak pedulikan. Pilihan otomatis ini berubah seiring waktu, dengan perangkat keras, perangkat lunak, deteksi yang lebih baik atau kemungkinan baru. Sangat penting untuk menyentuh sesedikit mungkin dari konfigurasi otomatis, untuk mendapatkan manfaat dari semua peningkatan dari penginstal-debian dan untuk dapat menjaga seminimal mungkin perubahan yang diperlukan untuk file preseed Anda dari waktu ke waktu dan untuk perangkat keras yang berbeda.
