So we have found out that the KNOPPIX 6.0.1 release is a BETA release, and hence does not have some features we want - specifically, it's not set up for persistence; there seems to be no way to get it to save the state and the user directories to persistent storage.

Furthermore, we have decided to install the older, released version, KNOPPIX v5.1.1, and have downloaded the KNOPPIX v5.1.1 ISO to the 2nd partition of the 4G USB stick which we installed v6.0.1.

Since the KNOPPIX v6.0.1 was missing some critical tools - telnet, K3B, etc - we have rebooted the HP machine called 'box' under Damn Small Linux (DSL) to perform this procedure.

The procedure is:

1. mount USB pendrive partition 1 (the VFAT partition with the CD ISO image for v6.0.1) into the DSL file system.
2. mount USB pendrive partition 2 (the ext3 partition with the copy of KNOPPIX_V5.1.1CD-2007-01-04-EN.iso) into the host (DSL) file system
3. copy the KNOPPIX v5.1.1 ISO file system from USB pendrive partition 2 to USB pendrive partition 1
4. perform the install tweaks given in USB KNOPPIX 5.1.1 persistent install from Linux | USB Pen Drive Linux on USB pendrive partition 1.

This should make the pen drive boot KNOPPIX 5.1.1 with persistence.

Note that both partitions on the existing USB pen drive are formatted as described in the installation document referenced above. That is, partition 1 is a 750M FAT16 partition for the CD image, and partition 2 is the remainder of the pen drive space (~3G in ths case) dedicated as an ext3 (Linux) file system.

Once the pen drive is bootable and persistent with KNOPPIX 5.1.1, it will be desirable to make partition 2 on the USB pen drive auto mount as the /home directory tree of the new system.

The method shown in the previous post worked – now posting from system running from USB stick.

This is a hybrid USB file system – partition one is 750M FAT16, partition two is the rest of the 4G USB stick, formatted as ext2, I believe.

Here are some vital stats copied from a console:

Used the instructions as shown for KNOPPIX v5.1.1 excepting only that I found no /cdrom directory on KNOPPIX v6.0.1. Used the /mnt-system directory instead as that appeared to be where the CD was mounted (according to df -h).

Testing Pendrive boot of KNOPPIX v6.0.1 this time 2009-09-07 EST 22:25.

Posting this from a disc-less host, using a KNOPPIX V6.0.1 LiveCD downloaded to the Vista host using BitTorrent / BitComet.

This KNOPPIX disc divined the correct network configuration from the USR5430 Ethernet / WiFi bridge, which is configured as part of an AdHoc wireless (802.11) LAN which has an Internet backhaul (configured using ICS) over a Cricket CDMA USB BroadBand modem on the Vista box.

The KNOPPIX network configuration routine psychically determined all that and configured it without having to ask me any stupid questions. That, all by itself, is freaking amazing. Contrast it, for instance, with DamnSmallLinux (DSL) [v?] which I just argued with all weekend about the identical configuration. The DSL solution required adding a eth0:1 interface as root to begin with – it got worse from there. …

So it just booted up and ran without question, so far pretty much everything working, it appears.

Notable Factoids

• no spkrs on this box, so not sure about sound
• spell checker in Iceweasel is set for German
• Iceweasel is the default browser
• Iceweasel comes with the NoScript plugin already installed (!!!)
• a /slick/ new [to me] desktop environment called ‘Lightweight X11 Desktop Environment’ (LXDE) - really nice

Oddities

Is it true that USB devices only boot if they are formated FAT/32? Some weirdness going on there. If TRUE, I could put my PortableApps and my KNOPPIX on the same 4G USB stick? Maybe?

Glitches

For some reason, the 2nd & 3rd times I tried to boot this CD on this box, it hung during the X11 initialization - I believe(d) that some BIOS changes I made may have affected this, so the current settings changed are:

• Legacy USB support: enabled
• Startup Diagnostics screen: disabled

These settings may not matter, or may be specific to this system. They are recorded here so I can refer to them later, if necessary ;)

The hanging of the X11 startup is critical, since the system will shut itself down when X11 exits, and I was unable to find a way to interrupt the shutdown from the console during the time the X server was running. This means that if X hangs on this CD, the system shuts down after a short timeout.

Out of 4 boot-up attempts, the two that have worked (first and fourth) were both simple "put the CD in and hard boot w/o going to setup or boot-device select menu" sequences.

Video Resolution Bug

The screen resolution only seems to go up to 800x600. This has to be an incorrectly selected video device driver, since this same video card will go up to 1600x1200 and has done so in the past.
