@ Avinash -

manually edit the /boot/grub/grub.cfg right before remaster, and comment out or remove all your other partitions except root /. Then, run remastersys and build, then restore it to the way it was.

Then grub update runs on the install and everything is discovered and works fine. (you only have to do this with two or more OS’s in some circumstances).

Just DO NOT FORGET to restore that config after you build the ISO. If you reboot you are going to have LOTS of fun otherwise.

@serpiko - I have done this. Start with xubuntu 10 cd, remove every single thing you do not need, add the firefox ppa and flash and java, burn and go.

Otherwise, if you need openoffice or libreoffice or other stuff like that which WILL push you beyond 700MB CD then burn to DVD’s and use those.

Honestly, I build these custom setups for coffee shops and airports, and I DO put it on a USB memory card reader, which I hook up INSIDE the computer. That way, the owner can open it up, install a newer version, re-lock the card, reboot and go. It is faster then a CD/DVD and upgradable, yet every bit as secure (assuming you do not have your machine in an area where they can take it apart, in which case there is no effective way to secure it)

I tried to customize a system for public libraries but had problems creating a cd iso smaller than 900Mb in order to fit in a CD instead of a usb-stick

USB sticks(thumb drives) are cheap at 16GB Could it be possible to do this and get over 4GB iso?
All numbers in ISO 9660 file systems except the single byte value used for the GMT offset are unsigned numbers. As the length of a file’s extent on disk is stored in a 32 bit value[4], it allows for a maximum length of less than 4 GB (more precisely, less than 4 GiB). (Note: Some older operating systems may handle such values incorrectly (i.e., signed instead of unsigned), which would make it impossible to access files larger than 2 GB in size.)
Based on this, it is often assumed that a file on an ISO 9660 formatted disc cannot be larger than 232 in size, as the file’s size is stored in an unsigned 32 bit value, for which 232 is the maximum.
It is, however, possible to circumvent this limitation by using the multi-extent (fragmentation) feature of ISO 9660 Level 3 and create ISO 9600 filesystems and single files up to 8 TB. With this, files larger than 4 GB can be split up into multiple extents (sequential series of sectors), each not exceeding the 4 GB limit. For example, the free software such as infrarecorder and mkisofs as well as Roxio Toast are able to create ISO 9660 filesystems that use multi-extent files to store files larger than 4 GB on appropriate media such as recordable DVDs.

Remastersys repo works, with the ‘karmic’ at the end, try that Joe, tested on Kubuntu 10.10 /32 bit/

Also it’s in Menu, no need to use the CLI syntax, BTW…

I have remastered ubuntu 10.04 and its working fine. Now i am distributing it in my college but the problem is that the remastered ubuntu has taken my own grub.cfg so when i installed it in other’s laptop or desktop , its windows doesn’t start..
But when i do sudo update-grub in ubuntu after booting, this problem gets disappeared and windows starts. But i have to add this sudo update-grub command in installation so that after installing both windows and ubuntu will start automatically without any problem. So how can i add script containing sudo update-grub during installation.
Please reply…

hello again

i tried remastersys on ubuntu 10.04:
“sudo remastersys dist myisoname.iso”

it seems every thing is good.
no error report and it create a cdfs i guess in /home/remastersys/remastersys
finally it tries to make iso file:
creating md5sum.txt for live cd/dvd
creating iso
creating iso.md5
md5sum: iso file : no such a file or directory

why it cannot create iso file?!
there is not any iso file in /home/remastersys?
is something missing?!

Thank you. Very simple and worked well.

For newbies, it can all be done without terminal. Just add the software source, install remastersys and then open the remastersys program in the Administration menu.

Remastersys works for simple systems only. It is not suitable for true remasters.

Hi, the remastersys repository is not available anymore since a long time. Do you know of alternative sources where one can get the remastersys tool ?

Best regards

Remastersys dont works with Ubuntu 9.10. With Ubuntu 9.04 it works perfect. No burned DVD starts after using remastersys backup (newest version) with ubuntu 9.10.

Hello. May you tell me if there are a similar tool to do the following work:
- As I don’t have a DVD burner I would like some application that allows me to automatically install Ubuntu and download and install all the applications I have installed in this moment. I’m not an english speaker, so if I didn’t result clear, please, let me know and I will do my best to explain it better.
