I followed the tutorial here but I'm stuck at the part where I need to add ''persistent'' on the ''kernel arguments list''. I don't know how to do that. Any help would be appreciated. Thanks!

Before you reboot there are only two things that you need to remember. When the Live CD menu gets displayed hit the key to enter “Other Options”. This will display the arguments that the Live CD passes to the kernel. At the end of this argument list just add a space and add the word “persistent”. This will instruct the Live CD to maintain and use persistence. That is all. Go for it!

enter image description here

To display this screen, immediately when you see the purple screen with the symbol at the bottom (seen immediately after the boot sequence starts) press Esc... If you got to the "try ubuntu screen" you missed the opportunity!

enter the word persistent as shown.

When you press F6 a pop-up menu will display. Press Esc to make this menu disappear then use the keyboard arrow keys to move to the position shown in the picture.

Is that menu still available in the more recent ubuntu releases? Is it just really fast (so you need to press a hotkey) to show it? – Portablejim Dec 19 '11 at 23:40
yes - this is the 11.10 screen I just ran up on a virtualbox guest. – fossfreedom Dec 19 '11 at 23:41
What am I doing wrong? – Portablejim Dec 19 '11 at 23:57

When you boot the flash drive, at the boot splash, hit the F6 button.

You will see the options listed at the bottom, navigate on the line with the options with the arrow keys, add in persistent

quiet splash persistent --

If it is working, you can edit syslinux.cfg on the flash driver. This file is your boot menu. Edit or add a new entry.

Note: When I use persistence, I use 2 menu entries, one with and one without persistence.

Also take care, persistence uses a bit of space if you update your packages. If you are going to do that, I would suggest a standard install. You might also want to just use a persistent home.

FWIW, you can do this graphically with unetbootin and the Universal USB Installer

unetbootin is in the ubuntu repositories and runs on Windows

Can I do this with a CD/DVD? – Felix Leveille Dec 19 '11 at 23:45
Depending on what exactly you want to do with a CD/DVD, almost certainly yes – bodhi.zazen Dec 19 '11 at 23:47
I'm talking about adding persistence option on my LiveCD(like the last pic) – Felix Leveille Dec 20 '11 at 0:12
yes, you can use your live cd or iso to make a persistent flash drive. – bodhi.zazen Dec 20 '11 at 0:17
