I need to install 10 PC which has identical setup and hardware. So i was trying remastersys but its failing. How can i resolve this or use something else to achieve this?

Updating the remastersys.log
cat: /home/remastersys/remastersys/tmpusers: No such file or directory
Cleaning up the install icon from the user desktops
Removing the ubiquity frontend as it has been included and is not needed on the normal system
Calculating the installed filesystem size for the installer
Removing remastersys-firstboot from system startup
 Removing any system startup links for /etc/init.d/remastersys-firstboot ...
   /etc/rc0.d/K20remastersys-firstboot
   /etc/rc1.d/K20remastersys-firstboot
   /etc/rc2.d/S20remastersys-firstboot
   /etc/rc3.d/S20remastersys-firstboot
   /etc/rc4.d/S20remastersys-firstboot
   /etc/rc5.d/S20remastersys-firstboot
   /etc/rc6.d/K20remastersys-firstboot
Making disk compatible with Ubuntu Startup Disk Creator.
Creating md5sum.txt for the livecd/dvd
Creating /var/tmp/custom.iso in /home/remastersys/remastersys
The iso was not created. There was a problem. Exiting

Follow up:

Method 1: CloneZilla way:

1) I am unhappy that there is nothing exist for this to recover/backup 11.10

2) Anyway i have to do it

3) I did not used the popular Clonezilla because it does not offer me iso

4) I downloaded: http://clonezilla-sysresccd.hellug.gr/download.html

a) created a bootable CD from that ISO

b) booted and followed those steps

http://clonezilla-sysresccd.hellug.gr/restore.html

c) i got a iso file with everyhing on it including boot-loaders

5) then in another system i used my same CD to restore my image

Have you already tried the other ways described here? help.ubuntu.com/community/LiveCDCustomization. I'm asking because I'd recommend this way to create a custom CD. –  Andrea Corbellini Apr 7 '12 at 14:04

Another two possibilities:

Relinux (a fork of Remastersys).

Or, what I do to clone a machine, is copy the entire disk with CloneZilla and clone the disk. Ubuntu is good at automatically reconfiguring when it finds itself on new hardware. There is one change you would have to make in three different files on each machine that you have cloned:

  • Change the computer name in /etc/hostname, /etc/hosts and /etc/samba/smb.conf (otherwise you will have conflicts on the network).

Method 2: ReLinux way

$ sudo cp -R usr /
$ sudo cp -R etc /
$ cat /usr/share/doc/relinux/README
 Relinux

- a script to remaster your Linux distribution easily

For more information, please visit http://relinux.sf.net/


How to configure:
=================
Type this into a Terminal window to generate the configuration file:

  cp /etc/relinux/relinux.conf ./relinux.conf
  sed -i 's:EXCLUDES="\(.*\)":EXCLUDES="\1 '`readlink -f ./relinux.conf`'":g' ./relinux.conf

Then open ./relinux.conf in your favorite text editor, and change the values as you wish.
Some splash images are stored in /etc/relinux/relinux/splash/
When you run the script, make sure that you are in the same directory.

How to use:
===========
Usage is as follows:

  sudo relinux clean [configfile]     -  Cleans the temporary build directory
  sudo relinux fullclean [configfile] -  Fully cleans the temporary build directory (including the ISO file)
  sudo relinux squashfs [configfile]  -  Generates a .squashfs file based on your system
  sudo relinux onlyiso [configfile]   -  Generates a .iso file, using the squashfs file generated by the previous command
  sudo relinux iso [configfile]       -  Runs the last 2 commands

/home/relinux/custom.iso is generated. It is recommended to run it inside a virtual machine before you release it.

The size of /home/relinux/custom.iso is 1.4G
You will need to burn a DVD/USB/Blu-Ray disk instead of a CD.

It is recommended to run 'sudo relinux clean' (without quotes) once you have burned and tested custom.iso
It will not delete custom.iso or custom.iso.md5

Perfectly worked.
