Structure

main.sh

  • drives all actions:
    • init - bootstrap the bare minimum: debian packages, config files, etc.
    • build - build all enabled plugins: trigger downloads, file processing
    • build-all - build even disabled plugins
    • start / stop / restart - handle services
  • points all plugins to source global variables from ./services/main (could be changed!)
  • provides global variables:
    • IP / Hostname

./services

  • make services modular
  • plugin.sh
    • manages all actions: downloads, file processing, template parsing
  • config.sh
    • holds plugin specific variables
  • ./main
    • configure settings:
    • variables
      • tftp root dir
      • hook: pxelinux or ipxe menus? so plugins could provide matching menue entries
  • ./tftp-hpa and other services:
    • templates for config files

./menues

  • make modular menues
  • branding
  • which menue to use: menu.c32 or vesamenu.c32, even use iPXE menues (may be broken by plugins)
  • create menu sections: (maybe a kind of hook for plugin-types?)
    • put plugins into sections
    • types: livesystem, rescue, tools, installer, etc.

./plugins

  • plugin contains all needed files

  • plugin.sh

    • manages all actions: downloads, file processing, template parsing

  • config.sh

    • plugin name
    • enabled: y/n
    • type: rescue, os, installer (must be one of the menue hooks)
    • depends: nfs, samba, etc.
    • plugin specific variables and settings

  • Modular pxelinux menu:

  • split menu in parts: Knoppix, Rescuezilla, Acronis, etc.

  • use settings.sh as configuration file, e.g. MENU_KNOPPIX=YES or MENU_NON-FREE=NO

  • create template files in ./resources: menu-knoppix.cfg, menu-rescuezilla.cfg

  • use INCLUDE command if possible https://wiki.syslinux.org/wiki/index.php?title=Menu#INCLUDE

  • read settings.sh and parse templates to fill in variables

  • iSCSI Target:

    • apt install tgt
      • zless /usr/share/doc/tgt/README.iscsi.gz
      • tgtadm --lld iscsi --op new --mode target --tid 1 -T iqn.2020-11.tld.ostrach:target1
      • tgtadm --lld iscsi --op show --mode target
      • tgtadm --lld iscsi --op new --mode logicalunit --tid 1 --lun 1 -b /dev/hdc1
      • tgtadm --lld iscsi --op bind --mode target --tid 1 -I ALL

  1. install tgt
  2. parse settings.sh and create tgt config files to:
  3. a Windows 10 DVD target (.iso under /srv/tftp/non-free/windows10.iso)

Remeber: Check if a iSCSI Tape-Target could be used to trick a Tape Backup Software to use HardDisks as Tapes
