= MAC Based booting =
Hello,


Currently Work on:
I am Andreas.
[[ /MACbasedBooting ]]
-----
Installing with PXE and FAI MAC Address based.


With this hooks and some small changes in dhcpd.conf (based on FAI-CD) every computer that boots fai become a MAC based config file in the pxelinux.cfg/ dir. May be in the future a GUI can use/change this information.  
These are some ideas, if you think they need a other location feel
free to move. But leave a short message that I can remove it from this page.

  ....

If you press <shift> key during pxe booting you can get a prompt.
 
Possible commands are:
mkboot HOST=local 
mkboot HOST=remove
.....
mkboot HOST=demohost
.....

<pre>
#! /bin/bash
# hook mkboot for fai.
# If you start this script on a fai client it copy, create or delete a pxe bootfile. It use the ethernet mac
# address of the fai client.

Hello,

I am Andreas.

These are some ideas, if you think they need a other location feel free to move. But leave a short message that I can remove it from this page.
