Автоматическая установка Debian c помощью TFTP и DHCP.

Создаем папку

 # mkdir /tftpboot/pxe/Debian

Скачиваем и распаковываем архив

 #  wget http://ftp.us.debian.org/debian/dists/lenny/main/installer-i386/
current/images/netboot/netboot.tar.gz  -O - | sudo sh -c "cat - 
| tar xzf - -C /tftpboot/pxe/Debian" 

Уже в имеющийся набор софта добавляем раздел Dedian Preseed

 label Dedian Preseed
    kernel /pxe/Debian/debian-installer/i386/linux
    append load initrd=/pxe/Debian/debian-installer/i386/initrd.gz
    locale=en_US console-keymaps-at/keymap=us hostname=debian
    domain=bezha.od.ua url=http://192.168.0.101/sysresccd/preseed.cfg

В директорию apache кладем файл preseed.cfg
