automatic=… можно убрать и ввести все данные в процессе инсталляции. method=ftp можно заменить на http, nfs directory:/pub/ALTLinux/Server/4.0.1/install надо подмонтировть на серваке (наприм: mount -o loop altlinux-server.iso /var/ftp/pub/ALTLinux/Server/4.0.1/install) Можно добавить к append initrd опции с необходимыми параметрами. # xdriver=amd # net=8139too

                     Welcome to ALTLinux 4.0 network installation



To start the installation enter 'server' and press <return>.

Available boot options:

  desktop   - Installation Desktop
  server    - Installation Server
  noacpi    - Installation Server - ACPI Disabled
# failsafe  - Installation - Safe Settings
  live      - Run Live System
  rescue    - Rescue System
  memtest   - Memory Test
  harddisk  - Boot from Harddisk
  work      - Boot test image

На сетевухе включаем загрузку по PXE и правим mac address в dhcp.conf

# service dhcpd reload
# mkdir /var/ftp/cd-desktop
# mount --bind /media/cdrom /var/ftp/cd-desktop

Так же можно запускать бездисковые станции, но надо подготовить образ операционки.
