h1.  Deal with updated pxeboot files without the need to delete or re-download them 

# 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

<pre><code>default linux

label linux

IPAPPEND 2

kernel ipxe.lkrn

append dhcp && chain <%25= foreman_url('gPXE') %25>

</code></pre>

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

<pre><code>#!gpxe

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

initrd <%25= "#{@host.url_for_boot(:initrd)}" %25>

boot

</code></pre>

# Make sure you have your (or default) kickstart template (kind: provision).

# In the association tab of the above templates select the desired "applicable operating systems".

# Go to "Operating Systems" and in the "Templates" tab select the respective "provision", "gPXE" and "PXELinux" templates (should be 3 templates in total).

# Now you can either assign the OS to some host group or simply edit some host and change its OS.

# That's it - verify it works!
