knoppix-installer

I started writing this document to help me understand the different types of installation options presented in the knoppix-installer, and to begin some documentation of them. As you will see this document currently quickly degrades into a run through of just what the installer does. I hope it is still useful to someone else.

Notes:

knoppix-installer is distributed from http://debian.tu-bs.de/knoppix/installer/ at this time (22nd November 2004), the latest version is 0.3.14 which was released on the 30th june 2004. knoppix-installer is written and maintained by Fabian Franz. To run knoppix-installer you can use "sudo knoppix-installer" or if you have an internet connection use "sudo knoppix-installer-latest-web" which will automatically get and use the latest version.


knoppix type installs and debian/beginner type installs are two quite different things. Debian type installs are very similar to a beginner type except that it runs system_services which changes (removes) the hardware detection system and uses a common command line for the kernel except for a few rescue type commands which carry on to the installed system. A beginner type install retains Knoppix's hardware autodetection and the full command line/cheatcodes.

Types of installation:

  • 1 Knoppix (hd swap services boot)
    • 1.1 A copy of the liveCD on hard disk
    • 1.2 Works exactly as the cd based system does except apt-get can be used to add more software and the system is no longer read-only.
    • 1.3 DOES NOT ALLOW MULTIPLE USERS! You are automatically logged in.
    • 1.4 Carries kernel command line to new system (i.e. Cheat codes) except for vga, initrd and BOOT_IMAGE
  • 2 Debian (hd swap name user userpass rootpass host services boot)
    • 2.1 Just carries acpi, noapic, nosmp, pci, pnpbios and noapm forward on the kernel command line
    • 2.2 Allows multiple users
    • 2.3 Bears the closest resemblance to a "normal" debian installation.
  • 3 Beginner Default (hd swap name user userpass rootpass host services boot)
    • 3.1 Uses Knoppix Hardware detection
    • 3.2 Allows multiple users
    • 3.3 Carries kernel command line to new system (i.e. Cheat codes) except for vga, initrd and BOOT_IMAGE


The general consensus seems to be that most problems and confusion arrive with people using the knoppix type installation so generally the debian or beginner type install are preferable. More experienced users will probably want the debian type install, users not familiar with setting up hardware may not want to follow them however. If you are going to use the beginner type be aware that you are still using the auto-configuration so you can change your cheatcodes, the flip-side is that changes you may think you are making permanently will be overwritten when you reboot. It is the balance of convinience of hardware setup (especially if you change hardware) Vs having a more regular installed linux (debian) system.

All installs go as follows:

  • 1 show_install_options
  • 2 do_install
    • 2.1 module_hd_doaction
      • 2.1.1 Format ($HD_FSTYPE = xfs, reiser, mkfs.*) if $HD_FORMAT

      • 2.1.3 mkdir $TARGET_MOUNT_POINT
      • 2.1.4 mount the partition
      • 2.1.5 mount from $HD_MAP
      • 2.1.6 module_hd_knoppix_copy
        • 2.1.6.1 cd /$DEFAULT_DIR
        • 2.1.6.2 cp -a $TARGET_MOUNT_POINT
    • 2.2 module_swap_doaction
      • 2.2.1 if $SWAP_AUTODETECT = no then foreach $SWAP_CHOICES echo $_ none swap defaults 0 0 > $TARGET_MOUNT_POINT /etc/fstab
    • 2.3 update_fstab
      • 2.3.1 write header into etc/fstab
      • 2.3.2 write / to etc/fstab (errors=remount-ro unless reiserfs|xfs)
      • 2.3.3 Add other $HD_MAP entries to etc/fstab
      • 2.3.4 Add swap devices, preserved by copying to temp
      • 2.3.5 Add CD-Roms/DVDs
        • 2.3.5.1 echo line to fstab
        • 2.3.5.2 mkdir for mounting
      • 2.3.6 Add automounter links (copy them from mnt to mnt)
      • 2.3.7 Knoppix detect other partitions
        • 2.3.7.1 in chroot mount /proc, rebuildfstab -r, umount /proc
      • 2.3.8 set ntfs to umask=000
      • 2.3.9 if $INSTALL_KANO make /dev/hd mount auto not noauto
      • 2.3.10 on vfat use noauto, users, exec, umask=000
    • 2.4 old_installer
      • 2.4.1 system_type_knoppix if KNOPPIX then return when finished
