h1. Net-install service

The Net-install service enables the Linux system installation by booting from the local network (PXE). This service is available on the VLAN51 (private lab network).

h2. Using the service

# Connect the computer to a ethernet plug configured to use the VLAN51

# Boot the computer by choosing Network Boot

# The computer should boot by showing a blue menu (Note: several tries may be needed, depending of the delay for the network switch to enable the ethernet port for your machine)

# Choose which system you want to install

# Follow OS install procedure

TODO: Explain systems alternatives (serial/gtk preseed)

Note: each Debian (and Ubuntu?) installed system is set up for using the lab mirror for packages installation. You may disable this by editing /etc/apt/apt.conf

h2. Administration

* The service is hosted by the server netboot.ipv6.enstb.fr (VM on virtualc5-3 KVM hypervisor). Login to this server is adminrsm.

* The netboot service is enabled using dnsmasq, with configuration located in /etc/dnsmasq.d/01_netinstall.conf

* The different installable systems images are located in /srv/tftp/netboot-installer

* Systems images can be added/removed by adding entries in /srv/tftp/netboot-installer/pxelinux.cfg/installer-entries

* Systems images may need to be updated (when kernel modules have been updated) :

** Look for installer mirror in /srv/tftp/netboot-installer/installers.txt

** Download MIRROR-URL/installer-{ARCH}/current/images/netboot/netboot.tar.gz

** Unpack in /srv/tftp/netboot-installer/{DIST}-{ARCH}/netboot
