if you're get fear from regexp:

ifconfig eth0|grep 'inet addr'|sed -e 's/[A-Z,a-z,:]//g'|awk '{print $1}'

Модификация Ubuntu LiveCD

Потребуются:

• 3-5гб свободного места
• 512мб оперативной памяти
• squashfs-tools
• genisoimage, mkisofs
• Ядро с поддержкой squashfs
• Виртуальная машина для тестов
• Образ Ubuntu Desktop

Итак, приступаем:

sudo apt-get install squashfs-tools genisoimage

mkdir ~/livecdtmp

mv $ubuntu_iso_image ~/livecdtmp

cd ~/livecdtmp

mkdir mnt

sudo mount -o loop $ubuntu_iso_image mnt

mkdir extract-cd

rsync --exclude=mnt/casper/filesystem.squashfs -a mnt/ extract-cd

sudo unsquashfs mnt/casper/filesystem.squashfs

sudo mv squashfs-root edit

sudo cp /etc/resolv.conf edit/etc/

sudo cp /etc/hosts edit/etc/

sudo mount --bind /dev/ edit/dev

sudo chroot edit

mount -t proc none /proc

mount -t sysfs none /sys

mount -t devpts none /dev/pts

export HOME=/root

export LC_ALL=C

Сейчас можно издеваться над дистрибутивом как вам угодно, вырезать у него пакеты, обновлять их, в общем время кастомизации настало. Для удобства вот пара команд:

dpkg-query -W --showformat='${Installed-Size}\t${Package}\n'|sort -nr|less

Выводит все установленные пакеты упорядочив их по уменьшению занимаемого размера

apt-get purge package-name

Удаление пакета

man gconf

Информация по настройке Gnome

После завершения издевательств над системой рекомендуется всё за собой подчистить:

aptitude clean

rm -rf /tmp/* ~/.bash_history /etc/resolv.conf /var/lib/dbus-machine-id

Теперь отцепляем все маунты и делаем ISO-образ

umount /proc

umount /sys

umount /dev/pts

exit

sudo umount edit/dev

chmod +w extract-cd/casper/filesystem.manifest

sudo chroot edit dpkg-query -W --showformat='${Package} ${Version}\n' > extract-cd/casper/filesystem.manifest

sudo cp extract-cd/casper/filesystem.manifest extract-cd/casper/filesystem.manifest-desktop

sudo sed -i '/ubiquity/d' extract-cd/casper/filesystem.manifest-desktop

sudo sed -i 'casper/d' extract-cd/casper/filesystem.manifest-desktop

sudo rm extract-cd/casper/filesystem.squashfs

sudo mksquashfs edit extract-cd/casper/filesystem.squashfs -b 1048576

sudo vim extract-cd/README.diskdefines

cd extract-cd

sudo rm md5sum.txt

find -type f -print0|sudo xargs -0 md5sum|grep -v isolinux/boot.cat|sudo tee md5sum.txt

sudo mkisofs -D -r -V "$IMAGE_NAME" -cache-inodes -J -l -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table -o ../имя_нового_образа.iso
