Step-by-step guide of the kickstart for Fermi Linux 7.1.1

• Get bootnet.img from the Fermi Linux server.
• Prepare configuration files, syslinux.cfg and ks.cfg.

  The kickstart configuration file, ks.cfg, is modified from the original RedHat sample, sample.ks. Their kickstart document says it is included in the distribution. I found it somewhere on the Web. Options are explained in a RedHat document.

  You have to specify the root password in ks.cfg. I was not comfortable writing plain text password and used encrypted one with the --iscrypted option. A simple C program can generate the encrypted password string. (I don't know how to use MD5 encryption, sorry.) The code can be used as following. You give a password and a two characters 'salt'.

  	    % cc encrypt.c -lcrypt
  	    % ./a.out
  	    your_pass_word aB<Return>
  	    aBXXXXXXXXXXX
  	    

  In the %packages section of ks.cfg, you can either specify individual RPM files or groups of RPM files. A file in the Fermi server gives a list of pre-defined 'package's.
• Create a modified boot image for a kickstart.

  	    % cp bootnet.img ks.img
  	    % sudo mount ks.img /mnt -t msdos -o loop
  	    % sudo cp syslinux.cfg ks.cfg /mnt/
  	    % sudo umount /mnt
  	    

• Now, you copy ks.img into a floppy disk and use it for a kickstart!

• The sample ks.cfg I showed above is for DHCP boot. If you want static IP address, change the network option. I have a simple script to generate static IP boot images for a list of machines.

  	    % cat hosts.list
  	    192.168.7.1	foo.fnal.gov
  	    192.168.7.2	bar.fnal.gov
  	    % sudo ls # just to get a privilege
  	    % ./staticip < hosts.list
  	    % ls
  	    ...
  	    ks.cfg.foo
  	    ks.cfg.bar
  	    ...
  	    ks.img.foo
  	    ks.img.bar
  	    ...
