Setting up for Remastering
Based on the Knoppix Remastering Howto
This remastering assumes the following:
- you are running Knoppix 3.8.2
- you have a linux filesystem with at least 6 GB of free space
Boot from the Knoppix CD
- boot: knoppix 3
knx_dev=/dev/hda3 # the device with 6GB+ of free space
knx_mnt=/mnt/hda3 # the mountpoint for the device
knx=$knx_mnt/knx # the sandbox folder in which you will remaster the ISO
# Mount the partition:
mount -o rw,dev $knx_dev $knx_mnt
mount # did it mount?
df -H $knx_mnt # is there 6GB+ of free space?
# Create a root directory to work in
# This will simplify cleaning up
mkdir $knx
cd $knx # did it make the sandbox?
pwd # can you play in the sanbox?
# make a 1 GB RAM swapfile, just in case
dd if=/dev/zero of=swapfile bs=1M count=1000
mkswap swapfile
swapon swapfile
swapon -s # is swapfile being used?
# make two target folders: one for the source and one for the final master CD
mkdir -p $knx/{master,source}
ls -la # are they there?
# Copy the cdrom files to your master directory :
( cd /cdrom &&
find . -size -10000k -type f |
xargs cp -a --parents --target-directory=$knx/master/ )
ls -la $knx/master/
# Copy the KNOPPIX files to your source directory :
cp -a /KNOPPIX/* $knx/source/
ls -la $knx/source/
# setup some preliminary files
# /etc/fstab
grep -e '\/proc' -e '\/sys' /etc/fstab > $knx/source/etc/fstab
cat $knx/source/etc/fstab
# /etc/resolv.conf
cat /etc/resolv.conf > $knx/source/etc/dhcpc/resolv.conf
cat $knx/source/etc/dhcpc/resolv.conf
Working in the chroot environment
# "chroot" into the source folder
chroot $knx/source/
# mount /proc
mount -t proc /proc proc
# add/remove packages
apt-get update
dpkg-query -W --showformat='${Installed-Size} ${Package}\n' | sort -n
deborphan
# deborphan | xargs apt-get -y remove
# apt-get remove --purge name-of-package-to-remove
apt-get clean
# leave the chroot environment
umount /proc
exit
Making the image
# make the compressed image mkisofs -R -U \ -V "KNOPPIX.net filesystem" \ -publisher "KNOPPIX www.knoppix.net" \ -hide-rr-moved -cache-inodes -no-bak \ -pad $knx/source | /usr/bin/create_compressed_fs - 65536 \ > $knx/master/KNOPPIX/KNOPPIX # make the ISO mkisofs -pad -l -r -J -v -V "KNOPPIX" \ -no-emul-boot -boot-load-size 4 \ -boot-info-table -b boot/isolinux/isolinux.bin \ -c boot/isolinux/boot.cat \ -hide-rr-moved -o $knx/knoppix.iso $knx/master
