eggs unattended install

Eggs unattended install Is based on simple scripts:

  • eui-create-image.sh creates the image;
  • eui-start.sh is copied into /usr/bin/
  • eui-users contains the list of users enabled to sudo WITHOUT password, it is copied to /etc/sudoers.d/;
  • eui-autostart-[xfce/cinnamon].desktop starts automatic installation at login and is copied to /etc/xdg/autostart.

The three files eui-start.sh, eui-users and eui-*.desktop are deleted from the destination directory as soon as the production of the image is completed

Creation of an EUI image

To create an ISO with unattended-install capability, proceed as follows:

cd /usr/lib/penguins-eggs/eui

If necessary, modify the eui-start.sh file sudo nano eui-start.sh to select the desired language, swap configuration, and other possible configurations given in the source.

Save and start the image creation:

./eui-create-image.sh

An image with fast compression will be generated, and the cuckoo command will be started to distribute it.

Note: once the image is created. simply start 'eggs cuckoo' to distribute it, no need to regenerate it

Differences of a UEI image versus a normal image

Self-starting of the installer is done through the following files:

  • /etc/sudoers.d/eui-users
  • /etc/xdg/autostart/eui-[xfce/cinnamon].desktop
  • /usr/bin/eui-start.ch

You can select a particular customization or create your own, at the moment I am trying to adapt the customization to the various languages and we have:

  • bg (Bulgarian)
  • br (Brazilian Portuguese)
  • de (German)
  • es (Spanish)
  • fr (French)
  • it (Italian)
  • nl (Dutch)
  • pe (Spanish Peru)
  • ru (Russian)
  • uk (ukrainian)

/etc/sudoers.d/eui-users

It is copied inside /etc/sudoers.d, MUST be owned by root and have rights 0440

live ALL=(ALL) NOPASSWD: ALL
artisan ALL=(ALL) NOPASSWD: ALL

/etc/xdg/autostart/eui-autostart-[xdce/cinnamon].desktop

It is the file that makes it possible to auto-start the installer: there are currently two working versions, one for XFCE and one for cinnamon;

Currently, customization of the installation, MUST be done by editing this file.

    #
    # FLAGS
    # -H, --halt            Halt the system after installation
    # -N, --none            Swap none: 256M
    # -S, --suspend         Swap suspend: RAM x 2
    # -c, --custom=<value>  custom unattended configuration
    # -d, --domain=<value>  Domain name, defult: .local
    # -h, --help            Show CLI help.
    # -i, --ip              hostname as ip, eg: ip-192-168-1-33
    # -k, --crypted         Crypted CLI installation
    # -n, --nointeractive   no user interaction
    # -p, --pve             Proxmox VE install
    # -r, --random          Add random to hostname, eg: colibri-ay420dt
    # -s, --small           Swap small: RAM
    # -u, --unattended      Unattended installation
    # -v, --verbose         Verbose
    eggs install --custom=it --domain=.local --random --nointeractive --halt
else  
    # isInstalled
    sudo rm -f /etc/sudoers.d/eui-users
    sudo rm -f /usr/bin/eui-start.sh
    sudo rm -f /etc/xdg/autostart/eui.desktop
fi

Note: look at the new --halt flag, introduced to shut down the machine after installation and avoid. thus, further attempts in the case of PXE-enabled computers and with first PXE boot device.

I am not very skilled at producing movies, even less so as an actor, I made this videos, I hope it will help you.
