Cobbler template files

Cobbler provides template files for dhcp/pxe/bind/dnsmasq configuration.
If you decide to manage there relevant services via cobbler, their configuration files are based on these templates that can be customized according to own needs.
Note that Cobbler overwrites and updates these configuration files if is configured to do that (for dhcp/dns/dnsmasq) every time you type cobbler sync.

/etc/cobbler/pxe/pxedefault.template
It's the main template file for PXE menu. Here you can change the PXE menus shown at boot time.  
This template replaces /tftpboot/pxelinus.cfg/default when cobbler sync is run.  
Important settings are:  
TIMEOUT: Idle Timeout. After this time PXE goes on with what is defined in ONTIMEOUT  
MENU TITLE: Just a string written at the beginning of the PXE menu  
DEFAULT: Default behaviour at PXE boot. Can be menu, to show the menu, the name of a label, to install what is defined in the label, local, to go on with a normal boot from local media.  
PROMPT: If set to 1 a simple prompt is shown.  
In the template $pxe_menu_items is replaced by all the systems and profiles configured in cobbler.
