PXE netboot

Via PXE / netboot, you can boot and install systems over network. Just switch the bios to PXE netboot.

You need dnsmasq, it includes a tftpd server, which serves the boot images.

dnsmasq config

Example config: 

dhcp-range=192.168.20.100,192.168.20.150,12h
dhcp-boot=pxelinux.0
enable-tftp
tftp-root=/var/tftpd
dhcp-option=3,192.168.20.1
dhcp-option=6,192.168.20.1

tftpd

dnsmasq includes a tftp server, you just need to serve the pxe boot files from there. For debian, you can use:

pxelinux.cfg/default

this includes the bootmenu and is started, as soon as the client boots via pxe/tftp. put your matching config here. 

# the debian installer. this is included in netboot.tar.gz

preseed

You can automat the debian installer, so all questions get answered automagically :)

Add a download url for the preseed file to the bootmenu in pxelinux.cfg/default. This can be served via nfs or web.
