The original never made it here, so I'll tag on unless you object.

<too late>

Get Ubuntu Dapper and burn it (it's up to Flight 7 now, I believe).
Then follow the instructions here:


Once you set it up and boot for the first time, you'll need to create a
user or settings won't be changed.

At the first boot, hit F6, type in 'persistent' (no quotes) and hit
enter. It will take awhile the first boot to populate the drive, but it
will eventually get there.

That and more are explained on the page.

2 things that might cause some distress which aren't mentioned:

1. Recreating the CD with 'persistent' already on the default
   commandline. In can be done, but remastering will need to be located
   on some other page(s) to do it. There are quite a few available that
   will explain it. You don't have to do this. You might not *want* to
   do this if you plan on running the CD in anything but persistent
   mode because it bombs really badly if it can't find a usable drive
   with the right name, although you could hit F6 and remove
   'persistent' from the commandline as well.

2. Booting up always goes to the wrong user (ubuntu). In a previous
   version (Flight 3? 4?) I had that changed. When I redid everything
   it came back. I tried editting gdm files manually and that didn't
   work. You can't edit the behavior of gdm from the login screen
   (although it will appear that it's going to for a few seconds after
   you manually create a root password).  There's no gooey editor in
   Gnome that I could find where it could be changed. I even removed
   the original user, but it seems to stick around anyway.  It can be
   done, I know, but I'm missing something this time around or
   something. (It's not like I spent more than about 20 minutes on it
   anyway, so I could easily be missing something simple.) The result
   is that one needs to log out & log back into the homemade user
   unless that part is changed. Otherwise settings won't be saved.

I've been using it on a 1G thumbdrive for several things (and recently
expnaded that to 3.5G of a 5G drive, which also has a swap partition
included to make things speed up). I even installed Crossover so I
could run some goofy work-related stuff that won't work (I tried) with
anything but IE, and that works fine on linux. The WIFI has saved
settings for the work laptop and the home laptop, so I can drop it into
either machine and just tell it which to use. And it has printer
definitions for both places as well. The gigger has ample room to save
important files, just so long as I don't get carried away (which I
usually do, and that's why I already got a bigger drive).

My next attempt will be to try running a second drive as a mount point
below the casper-rw drive to see if I can expand it all and allow some
new possibilities. And to fix the default user thing again.

Now there's a man with an open mind - you can feel the breeze
from here.
