Running Linux Installers from Windows Remote Installation Service (RIS)

There may be a time when you need to use some ancient Windows software to deploy a Linux O/s... setting up a Linux PXE / TFTP system is no fun at all and far too obvious a solution! Anyway here's how to use RIS (WDS running in Legacy) to launch a Linux network install (or could be a LiveCD etc...)


RIS looks for a .sif file in your images folder, so make a new folder for your install then create a /i386/templates/pxelinux.sif file (you can call it whateveryoulike.sif) and it needs the following -

[OSChooser]

Description="Whatever You Are Installing"

Help="Linux install blah blah blah"

LaunchFile="%INSTALLPATH%\%MACHINETYPE%\templates\pxelinux.0"

ImageType=Flat

Version="1.00"

 Version can be whatever you like, as can the description and help. You need to copy pxelinux.0 from your distro to \templates and from there it basically runs the same as it would on a Linux PXE/TFTP server... so have a look at instructions on how to get that working from there.

pxelinux.0 looks for a pxelinux.cfg directory which usually has a file "default" which is a plaintext file detailing the boot menu and pointing to the relevent initrd.img file you're trying to load... there will probably be one of these files in your linux distro's isolinux dir and you can mess around with it to give different boot options.

Anyway thats basically how it's done, information from a variety of sources and some trial and error!

Have to offset the massive geekery somehow!!!

Fedora 13 Kickstart Disk Partitioning

Work asked me to create an auto install of Fedora 13 that resizes a Windows XP install automagically... here's the results of some hair pulling and tomgeekery!!!

In your ks.cfg -

%pre
#get partition scripts / files
wget -P/tmp http://IPADDRESS/partition.sh 
sh /tmp/partition.sh >> /tmp/partition.log

 partition.sh -

#!/bin/bash
##############################################################################
#Made by Long Tom 2010
#Script resizes 160GB Windows disk to 80GB ntfs, 76GB linux & 4GB swap
#Procedure (tested manually)
##resize windoze partition
#ntfsresize -f -s 80G /dev/sda1 (works)
#Now fdisk - Delete sda1, recreate new NTFS at half size and toggle bootable
#parted can now use free space
##make a root linux partition
#parted mkpartfs primary ext2 start end
#partition remaining for swap
#parted mkpartfs primary linux-swap start end
##format the filesystems, installer can change to ext3 / 4 later on

##########    Getting the numbers

#First need to get disk size(s)   
dev=`fdisk -l | grep -m 1 Disk | grep bytes | awk '{print $2}'`    #gives something like - Disk /dev/sda: 500.1 GB, 500107862016 bytes
bytes=`fdisk -l | grep -m 1 Disk | grep bytes | awk '{print $5}'`

dev=${dev%:}    #strip of : from end

#get RAM
mem=`cat /proc/meminfo | grep MemTotal | awk '{print $2}'` #gives memory in kB

#echo "$memk"

let kbytes=$bytes/1000

echo "First disk drive $dev"
echo "Total size $kbytes kB"
echo "System memory $mem kB"    #we'll use this as swap partition size

#so half size of disk -
let halfPartSize=$kbytes/2

echo "Windows partition will be $halfPartSize kB"
echo "Swap will be $mem kB"
echo "Linux will be whatever's left!"

one="1"

dev1=$dev$one    #gives /dev/sda1
let halfPartSizeK=$halfPartSize*1000    #ntfsresize needs kb

##########    Resize windows partition
echo "Now running ntfsresize -f -s $halfPartSizeK $dev1"
ntfsresize -f -s $halfPartSizeK $dev1

##########    Check to see if previously partitioned - if so skip fdisk +hope!!!

#if [`fdisk -l | grep sda2`

##########    Make fdisk.commands file with fdisk scripting

K="K"
plus="+"
halfPartSizeK=$plus$halfPartSize$K
linuxK=$plus$mem$K
#swapStartK=$plus$swapStart$K

echo "d" > /tmp/fdisk.commands    #delete

echo "w" >> /tmp/fdisk.commands    #write & quit

##########    Now run fdisk

echo "Now running fdisk $dev"

fdisk $dev < /tmp/fdisk.commands

echo "Now running parted to format linux partitions"
parted -s $dev mkfs 3 ext2
parted -s $dev mkfs 2 linux-swap

exit 0

Get that for some dodgy scripting!!! hehehe works though :P
