9.10 Thumb Drive with Persistent Changes

[caoinan]

I've just installed UNR version of Ubuntu on one of my thumb drives and was wondering what I needed to do to for making it have persistent changes? I've seen the different tools and the usb creator they have on Ubuntu already but I want to do it myself from scratch. What files do I need to edit to make the drive persistent? I made the bootable thumb drive using UNetbootin.
Thanks

You can make an ext2, 3 or 4 Partition and name it casper-rw. this partition will hold your persistence.
Here is a bit of a how to:

Boot Live CD.
Plug in flash drive.
Start Partition Editor
Create 1 GB FAT32 partition, (on the left side of the bar). (size is optional)
Create a 1.5 GB ext3 partition to the right of this, labeled it "casper-rw". (ext2 and ext4 also work).
Create a partition in the remaining space and label it "home-rw". (optional, creates a separate home partition)
Close Partition Editor.
Un-mount and re-mount flash drive.
Start "Create a live usb startup disk", (usb-creator).
Select "Discard on shutdown".
Press "Make Startup Disk.
When usb-creator finishes, run "gksu nautilus"
Select disk / syslinux / text.cfg and added "persistent" as shown below:
append noprompt cdrom-detect/try-usb=true persistent file=/cdrom/preseed/ubuntu.seed boot=casper initrd=/casper/initrd.gz quiet splash --
Shutdown, remove CD, reboot.
You are persistent.

If you want a how to for doing the same thing with an UNetbootin install let me know.

Oops, on closer inspection I notice that you did your install using UNetbootin:


This is how I made a Unetbootin install to flash drive persistent.
Booted Live CD, (Live USB should also work)
Plugged in target flash drive.
Started Partition Editor
Created 1 GB FAT32 partition, (on the left side of the bar).
Created a 1.5 GB ext3 partition to the right of this, labeled it "casper-rw".
Created a ext3 partition in the remaining space and labeled it "home-rw".
Closed Partition Editor.
Un-mounted and re-mounted flash drive.
Started Windows, started Unetbootin, selected Diskimage, located the iso, selected Type = USB Drive, selected correct drive letter
Pressed OK, waited 5 minutes.
When Unetbootin finished, shutdown, booted thumbdrive.
At boot menu hit Tab, then typed "(space)persistent"
Ran "gksu nauilus", opened filesystem / cdrom and then opened syslinux.cfg with text editor.
Added "persistent" as shown below:
append initrd=/ubninit file=/cdrom/preseed/ubuntu.seed boot=casper quiet splash -- persistent
Rebooted, changes were persistent.

Ok. I'm at work right now I'll try it when I get home or if I get a chance I'll try it here at work. Thank you.
[EDIT]
The reason I didn't want to use Ubuntu's USB Creator is because it seems to boot up kind of slow compared to using UNetbootin to make the bootable thumb drive.

Thanks Cameron I got it to work now.
