Summary
The goal is to boot Knoppix from the HDD using a bootloader (grub) and three files: the ISO, a swap file, and a persistent disk image (PDI).
Version 1: copy files from CD
Part 1: copy the files from the CD
- boot with knoppix from the CD (aka PMI - Poor Man's Install)
knoppix dma noswap vga=0 1
- if you modify the environment variables, you should be able to copy and paste straight into a terminal
# set environment variables drive=/dev/hda partition=/dev/hda1 mountpoint=/mnt/hda1 grub_partition="(hd0,0)" # hda1 = hd0,0 -- format is (device,partition) # clear the entire drive - yes, all information will be lost { seq -f d$'\n'%g 64 -1 1 echo "w" } | fdisk ${drive} >& /dev/null fdisk -l ${drive} # Partition drive, creating a 1 GB partition that has the bootable flag set echo -e "n\np\n1\n1\n+1G\na\n1\np\nw" | fdisk ${drive} fdisk -l ${drive} # create filesystem mkfs.ext2 ${partition} # rebuild /etc/fstab rebuildfstab -r # mount the partition mount ${mountpoint} # install grub grub-install --root-directory=${mountpoint} ${drive} # copy the files from the CD to ${partition} cp -a /cdrom/ ${mountpoint}/knx402 ls -la ${mountpoint}/knx402/KNOPPIX/KNOPPIX # create /mnt/hda1/boot/grub/menu.lst cat <<eof > ${mountpoint}/boot/grub/menu.lst timeout=5 default=0 title Knoppix 4.0.2 from ext2 hda1 ISO scan ramdisk=32MB kernel ${grub_partition}/knx402/boot/isolinux/linux \\ ramdisk_size=100000 init=/etc/init lang=us \\ apm=power-off vga=0 nomce quiet fromhd=${partition} \\ knoppix_dir=knx402/KNOPPIX config=scan home=scan \\ ramdisk=32768 noprompt noeject -b 1 initrd ${grub_partition}/knx402/boot/isolinux/minirt.gz boot title Memory test kernel ${grub_partition}/knx402/boot/isolinux/memtest eof wc -l ${mountpoint}/boot/grub/menu.lst # unmount hda1 umount ${mountpoint} # boot from the HDD reboot
Part 2: create a swapfile
- boot knoppix from the HDD using grub
- on entering emergency mode, execute these commands:
mount -o remount,rw /cdrom dd if=/dev/zero of=/cdrom/knoppix.swp bs=1M count=40 mkswap /cdrom/knoppix.swp chmod 0600 /cdrom/knoppix.swp swapon /cdrom/knoppix.swp swapon -s reboot
- to use on reboot, modify /etc/init.d/knoppix-autoconfig. Unfortunately, one has to do this each time at reboot.
Part 3: create a persistent disk image
- boot knoppix from the HDD using grub
- on entering emergency mode and modifying knoppix-autoconfig, execute these commands:
rebuildfstab -r knoppix-mkimage # choose the defaults and the maximum size for a PDI exit
- to use on reboot, modify /etc/init.d/knoppix-autoconfig.
modifying knoppix-autoconfig to use swap and/or PDI
- Unfortunately, one has to do this each time at reboot.
{ cat <<"eof" 1059c1059 < ext3|ext3|reiserfs|xfs) MOUNTOPTS="$MOUNTOPTS,noatime" ;; --- > ext2|ext3|reiserfs|xfs) MOUNTOPTS="$MOUNTOPTS,noatime" ;; eof } | patch /etc/init.d/knoppix-autoconfig exit
- one solution is to put the above commands into a script saved as /cdrom/knx402/knx.sh. Then once one enters emergency mode all one has to do is type:
/cdrom/knx402/knx.sh

So far, booting with this PDI hasn't worked. Looks like theres a bug in /etc/init.d/knoppix-autoconfig. The code has two RegExs for ext3 and none for ext2. The solution is to boot using the -b cheatcode, modify /knoppix-autoconfig, and continue booting. Then the PDI is recognized and mounted. # misc boot lines and commands knoppix dma noprompt noeject vga=0 -b 1 tune2fs -O ^has_journal /dev/hda1
