This is a technical description of the knoppix-installer. For a user-friendly HD installation guide, please see the Hd Install HowTo.

The knoppix-installer was written and maintained by Fabian Franz but now appears to be collaborative effort between Fabian, Klaus Knopper, and Kano of Kanotix. To run knoppix-installer you can use the command:

sudo knoppix-installer

If you have an internet connection use the command:

sudo knoppix-installer-latest-web

It 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:

  • Debian (hd swap name user userpass rootpass host services boot)
    • Prefered method of HD install.
    • Just carries acpi, noapic, nosmp, pci, pnpbios and noapm forward on the kernel command line
    • Allows multiple users
    • Bears the closest resemblance to a "normal" debian installation.
  • Knoppix (hd swap services boot)
    • A copy of the liveCD on hard disk
    • 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.
    • DOES NOT ALLOW MULTIPLE USERS! You are automatically logged in.
    • Carries kernel command line to new system (i.e. Cheat codes) except for vga, initrd and BOOT_IMAGE
  • Beginner Default (hd swap name user userpass rootpass host services boot)
    • Uses Knoppix Hardware detection
    • Allows multiple users
    • 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 or beginner type of installation. The debian type install is prefered. 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) versus having a more regular installed linux (debian) system.
