TFTP server disclaimer

Maintenance advise

For each kernel you add, you should create a small README file.

Ex: /tftpboot/images/README.txt or /tftpboot/sources-images/README.txt


# README file version 1.1 - January 2015 - Guillaume Diaz

# Image "trusty" ==> Ubuntu 14.04 LTS kernel 3.13.0-44-generic | January 2015


Global disclaimer

I advise you to put the following test inside your /tftpboot/README.txt directory:


# README file version 1.1 - January 2015 - Guillaume Diaz

#--------------------------------
# IMAGES CREATION
#--------------------------------

You can have many images over here.

Definition: 
image = a kernel that will be loaded by the NetBoot client. 


Composition:
each image must have a "vmlinuz" + "initrd.img" file. 

No matter where you pick these files from - locally or remotely - but don't forget to:
* Configure the "/etc/initramfs-tools/initramfs.conf" to support NetBoot + NFS
* Enable all kernel modules + server reboot before copying the "vmlinuz"
* Don't forget to do a "mkinitramfs" on the target "initrd.img" using your own 'initramfs.conf' 
* Don't forget to copy the kernel sources files into the target netboot NFS share in "/lib/modules/`uname -r`" + "/usr/src/linux-headers-`uname -r`" 


Hint:
If you plan to serve different flavors of the same distribution (ex: ubuntu | Xubuntu | Lubuntu) then you can use the same kernel for all of them.



#--------------------------------
# IMAGES USAGE
#--------------------------------

Each image matches a specific kernel version. 
>> That's the version you have to install on your NFS image!
   Also, you need to put the /tftboot/source-images kernel modules + libraries into the target NFS image.



Enjoy!
