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
