Install with iPXE and unattend

[ymolinet]

HI all,

I'm searching how to install pFsense from iPXE (based on last 2.1 build i386) based on http
my test with this command don't work :

kernel http://192.168.1.100/pfsense-installer/boot/pxeboot
wherer pfsense-installer is the ISO content.

or

kernel http://192.168.1.100/memdisk
initrd http://192.168.1.100/pfsense-installer/pfSense.iso iso raw

In addition, I'm searching how to install pFsense in silent mode with an unattend file (like preseed for debian).
I found only a topics to change the default config.xml file in the ISO.

My Goal is to deploy pfsense from pxe with a config.xml file available out of the iso (http://192.168.1.100/config.xml)

Thanks for your help,
Yannick
