Ok, i've spent 3 days now trying to get persistent storage on an Ubuntu USB 
installation to work.
It fails on karmic too....

Not even when using the initrd.gz + /etc/init.d/casper update listed in
this thread, do i get it to work :((

The basic install and startup of Ubuntu from USB works, but saving
_anything_ (including only a change of desktop background), results in a
failure to boot up after restart.

The error consistently seems to be these write-errors on shutdown of the USB 
installation:
* possibility 1: 
        Buffer : I/O error @somesector (repeated slightly more than a dozen 
times on different sectors)
* possibility 2:
        end_request : I/O error (also slightly more than a dozen times on 
different sectors)

I tried:
* Creating with usb-creator-gtk (Administration -> USB Startup Disk Creator), 
on Ubuntu 9.04 jaunty, to a good 4Gb USB key, using the latest .iso for 9.04 to 
install:
        * Using persistent storage at all: fail.
        * Using a persistent space of only 300Mb: fail.
        * Disabling HAL polling before reboot on first change of running Ubuntu 
USB : fail
        * (Tag 1) Updating the initrd.gz before booting from the usb-key with 
the one provided by Steve in this thread (comment #60), then when booted 
perform the update described in comment #66:
                Only 2 write-errors on shutdown of USB installation, but fails 
to boot next time round.
        
* Creating with usb-creator-gtk on Ubuntu 9.10 Karmic, to the same 4Gb USB key, 
using either 9.04 iso for install or even the 9.10-beta.iso:
        * Fail, error remains.
        * Using (Tag 1): Fail.

* Creating with "Portable Linux" (http://rudd-o.com/new-projects/portablelinux):
        * Using ubuntu 9.04 install iso: Fail.
