Deal with updated pxeboot files without the need to delete or re-download them¶

1. In your foreman instance, go to "Provisioning templates".Create a new template (kind: PXELinux) and have the following in the body:
   ( You'll need to have the ipxe.lkrn file in your tftpboot directory. Can be downloaded from here attachment:ipxe.lkrn
   

   default linux
   label linux
   IPAPPEND 2
   kernel ipxe.lkrn
   append dhcp && chain <%25= foreman_url('gPXE') %25>
   

2. Make sure you have a template (kind: gPXE) with the following in the body:
   

   #!gpxe
   kernel <%25= "#{@host.url_for_boot(:kernel)}" %25> ks=<%25= foreman_url("provision")%25>
   initrd <%25= "#{@host.url_for_boot(:initrd)}" %25>
   boot
   

3. Make sure you have your (or default) kickstart template (kind: provision).
4. In the association tab of the above templates select the desired "applicable operating systems".
5. Go to "Operating Systems" and in the "Templates" tab select the respective "provision", "gPXE" and "PXELinux" templates (should be 3 templates in total).
6. Now you can either assign the OS to some host group or simply edit some host and change its OS.
7. That's it - verify it works!
