This article focuses on "how to ubuntu DIY a ubuntu release of your own". Interested friends may wish to have a look at it. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn how to ubuntu DIY a ubuntu release of your own.

$export WORK=~/diy_ubuntu

$mkdir-p $WORK

Then we hang the CD image file to / mnt

$sudo mount-t iso9660-o loop dapper-live-i386.iso / mnt

$cd $WORK

Copy files CD files

$mkdir ubuntu-livecd

$cp-a / mnt/. Ubuntu-livecd

$chmod-R Uttw ubuntu-livecd

$sudo umount / mnt

Since the CD contains a lot of free software under windows, let's delete unnecessary files. Of course you can keep it.

$rm-rf $WORK/ubuntu-livecd/programs

Hang up the compressed files on the CD so that you can see a complete linux operating system directory in the $WORK/old directory later.

$mkdir $WORK/old

$sudo mount-t squashfs-o loop,ro $WORK/ubuntu-livecd/casper/filesystem.squashfs $WORK/old

We set up a 2GB-sized file system, then format the file as a device file, and the system gives a warning, ignore it, and choose yes.

$sudo dd if=/dev/zero of=$WORK/ubuntu-fs.ext2 bs=1M count=2147

$sudo mke2fs $WORK/ubuntu-fs.ext2

Then we hang up the empty file system.

$mkdir $WORK/new

$sudo mount-o loop $WORK/ubuntu-fs.ext2 $WORK/new

Copy files from the linux operating system. Since the linux we got in advance is compressed, we decompressed it.

$sudo cp-a $WORK/old/. $WORK/new

Of course, $WORK/old is of no use now. Scrap it.

$sudo umount $WORK/old

First of all, let's get into the operating system we just got.

$sudo cp / etc/resolv.conf $WORK/new/etc/

$sudo mount-t proc-o bind / proc $WORK/new/proc

$sudo chroot $WORK/new / bin/bash

Now you are in the system, shouting linux for human beings, refining ubuntu, and doing whatever you want.

# vi / etc/apt/sources.list # choose the source that suits you

# apt-get update

# apt-get dist-upgrade

# apt-get install the software you want to install

# apt-get clean

.... # more configurations

* leave your operating system

# exit

$sudo umount $WORK/new/proc

$sudo rm $WORK/new/etc/resolv.conf

Now you're back to your original state.

Reorganize the manifest.

$sudo chroot $WORK/new dpkg-query-W-- showformat='$ {Package} ${Version}\ n'> $WORK/ubuntu-livecd/casper/filesystem.manifest

Then do a "disk cleanup".

$sudo dd if=/dev/zero of=$WORK/new/dummyfile

$sudo rm $WORK/new/dummyfile

Recompress the system

$sudo rm $WORK/ubuntu-livecd/casper/filesystem.squashfs

$cd $WORK/new

$sudo mksquashfs. $WORK/ubuntu-livecd/casper/filesystem.squashfs

All your changes have been saved. Now get rid of $WORK/new.

$cd $WORK

$sudo umount $WORK/new

Recalculate the md5 of the file

$cd $WORK/ubuntu-livecd

$sudo find. -type f-print0 | xargs-0 md5sum | sudo tee md5sum.txt

Set up a CD image, the command is very long, put up with it.

$cd $WORK

$sudo mkisofs-o ubuntu-new.iso-b isolinux/isolinux.bin-c isolinux/boot.cat-no-emul-boot-boot-load-size 4-boot-info-table-r-V "My Cool Ubuntu Live CD"-cache-inodes-J-l ubuntu-livecd

Then you can burn the CD with iso.
