Разделение репозитория Ubuntu на DVD

Устанавливаем необходимый набор инструментов

Для выполнения поставленной задачи нам понадобится интерпретатор языка ruby и пакет debpartial для деления репозитория.

aptitude install debpartial ruby

Распределяем содержимое репозитория

Распределяем содержимое репозитория на 4 части объема

debpartial --nosource --dirprefix=ubuntu --section=main,restricted,universe,multiverse --dist=feisty,feisty-updates,feisty-backports,feisty-security --size=DVD /home/ftp/feisty/ /home/ftp/iso/

Копируем необходимые файлы

Исполняем программу на языке ruby, которая сформирует для нас необходимую структуру файлов и папок в 4 директориях.

ruby debcopy /home/ftp/feisty/ /home/ftp/iso/ubuntu0
ruby debcopy /home/ftp/feisty/ /home/ftp/iso/ubuntu1
ruby debcopy /home/ftp/feisty/ /home/ftp/iso/ubuntu2
ruby debcopy /home/ftp/feisty/ /home/ftp/iso/ubuntu3

debcopy

#!/usr/bin/ruby
#
# debcopy - Debian Packages/Sources partial copy tool
#
# Usage: debcopy [-l]  
#
#  where  is a top directory of a debian archive,
#  and  is a top directory of a new debian partial archive.
#
#  debcopy searches all Packages.gz and Sources.gz under /dists
#  and copies all files listed in the Packages.gz and Sources.gz
#  files into  from . -l creates symbolic links
#  instead of copying files.
