Использование approx

Approx - это такая приблуда, установленная на одном компутере и слушающая 9999 порт. На всех компутерах настроены /etc/apt/sources.list на использование этого approx'а.

Вот фрагмент клиентского sources.list:
deb http://approx.local.net:9999/debian1 stable main

А вот фрагмент настройки аппрокса /etc/approx/approx.conf:
debian1 http://ftp.debian.org/debian

В результате, когда клиент обращается на "...:9999/debian1 stable main", то аппрокс видит ключевое слово debian1 и подставляет вместо него "http://ftp.debian.org/debian" (получается http://ftp.debian.org/debian stable main)  и скачивает необходимый пакет в свой кэш. После чего выдаёт его всем запросившим.

На одной машине в сетке устанавливаем approx:
$ aptitude install approx
В отдельной папке /var/cache/approx будут храниться скаченные пакеты. Перенастраиваем approx.conf на обслуживание локальных дебианов и убунт и перенастраиваем клиентов. Радуемся.

Была проблема. Создал раздел на винте для кэша аппрокса. Перенёс туда существующие директории кэша (для дебиана) и прописал в /etc/fstab автоматическое подцепление этого раздела в каталог /var/cache/approx.
Создал машину на убунте и не смог её обновить через аппрокс. Включил в аппроксе дебаггинг и увидел, что аппрокс не мог создать новые каталоги в кэше для клиента убунты. Не хватало прав. Назначил права и всё заработало.
