remaster your own Kubuntu LiveCD

donkey42 · 05-10-2007, 06:52 PM

this is only for users or Linux, do NOT type these commands in Windoze as the outcome is unknown & could be catastrophic

a broadband connection is almost essential when downloading a LiveCD unless you like banging your head against a wall

to start with you need an original LiveCD, in this example we'll use Kubuntu Feisty Fawn 7.04
this is how you add / remove any software to / from a LiveCD by remastering the LiveCD (makeing a new custom LiveCD)

to begin you need a Feisty LiveCD you can download one from here remember where you downloaded it to (e.g. ~/Desktop)

now to save typing we'll rename the LiveCD you downloaded to feisty.iso by changing to the directory you downloaded it to

Off Topic:

mine is in ~/Desktop, start konsole and

Code:

cd ~/Desktop

rename it with

Code:

rn kubuntu-7.04-desktop-i386.iso feisty.iso

next we need to "Loopback mount" the .iso enter but first we need to create the directory "/mnt/loop"

Code:

mkdir /mnt/loop

or you can create the directory graphically, next, this command makes the LiveCD you downloaded is accessible in /mnt/loop

Code:

mount -o loop /path/to/feisty.iso /mnt/loop

now we need to create a directory / folder Kubuntu-rebuild in "~/"

Off Topic:

mine is /home/dave

rsync -ax loop /path/to/LiveCD.iso /mnt/loop/. kubuntu-rebuild

assuming you downloaded it to desktop your will be ~/feisty.iso

now we'll do a bit of preparation
next we'll use SquashFS & squashfs-tools (installable using your fav package manager or atp-get
now we'll loopback mount the filesystem

Code:

mount kubuntu-rebuild/casper/filesystem.squashfs /mnt/loop -t squashfs -o loop

now /mnt/loop contains the compressed ubuntu from the LiveCD, now copy /mnt/loop to a new directory in your home diiretory (/home/<username>), so, now we have the compressed CD in our home directory (~/kubuntu-source) and[code]rsync -av /mnt/loop/. ~/kubuntu-source you can now unmount /mnt/loop now copy your /etc/resolv.conf to ~/kubuntu-source/etc and

Code:

chroot ~/kubuntu-source

now you basically running the LiveCD without booting it

now comes the fun bit

Off Topic:

fun, yeah right

we'll now remove any software we don't need or want (but be very careful you don't remove something essential) & add any software we want, you can install or remove any software as you would normally would (for example with apt-get) anything you add / remove will be on the final LiveCD you are making, so, if you want Gparted on your LiveCD (as partition manipulation is always useful)

Code:

apt-get install gparted

Edit: after typing "exit" you can pretty much leave the remastering alone, & you can continue with it later, if you reboot before issuing the exit command, next boot you can continue as normal (just pretend you did type exit) as exit changes the root back to /

when you've finished playing with it type "exit" to leave the kubuntu LiveCD, now we'll make a list of files that will be on your remastered LiveCD by entering this daddy of most commands

Code:

sudo chroot kubuntu-source dpkg-query -W --showformat='${Package} ${Version}\n | grep -v deinstall > ~/kubuntu-rebuild/casper/filesystem.manifest

ok, last bit

now we need to rebuild the SquashFS filesystem image

BTW: this command takes a while to complete too

Code:

mksquashfs kubuntu-source/ kubuntu-rebuild/ casper/filesystem.squashfs -noappend

next we should update the MD5 checksums to varify the .iso is completed & works with

Code:

(cd /kubuntu-rebuild && find . -type f -print0 | xargs -0 md5sum > md5sum.txt

and finally we can build a brand new .iso image

Code:

mkisofs -r -V "My Custom Kubuntu" -cache -iodes -J -l -b isolinux.bin -c isolinux.bin -c isolinux/ boot.cat -no-emul-boot -boot-load-size 4 -boot info-table -0 newkubuntu.iso kubuntu-rebuild

your new Kubuntu Live is called newkubuntu.iso

BTW: i haven't completely done this yet, but it works

also (i think) this is the way it should be done, however, there are easier ways like UNK Reconstructor & i'm sure you can find more

Thanks for the information

.
But let's say I want to integrate a driver. When I load the live CD and I install it, are the integrated parts also installed?

as with any LiveCD, most hardware will be supported (unless you remove say NVIDIA driver while remastering)

however, like Windoze only generic drivers are included & not every conceivable hardware driver

can you integrate a driver a specific driver (not grfx & HDD, because thats slipstreaming) in Windows ?

but to answer your question: a LiveCD already contains a lot general hardware drivers on a LiveCD (unfortunatly less than Windoze) just don't remove any important stuff while remastering your LiveCD

however, i believe most windoze hardware is beta tested on *nix because *nix is more configurable

hope that answers your question RH

Off Topic:

not bad, off the top of my head

Edit: it is possible to transfer a working system to a LiveCD which includes all specific drivers

i think the easiest way to integrate drivers, as you say, is to create a LiveBackup, as detailed here, although i've never tried it, however i may be wrong, plese tell me if i'm wrong guys!

BTW: thankies for testing me RH

Yes, that's possible.

Linux and Windoze are built completely different. Windows is built on DOS, and Linux is built on UNIX. So drivers need to be rewritten for *nix systems.

But thanks anyway

Off Topic:

I would suggest to write that the above steps need to be done in a Linux environment, because it is possible that some people try to enter those commands in the Windows Command prompt
