Ubuntu :: 10.04 On USB Stick - Persistence Feature
Jun 18, 2010
The Pendrive Linux site states the following in regards to a USB Flash Install using their Universal USB Installer:
"Once finished, you should have a Live USB Ubuntu 10.0 that can be run directly from your Flash Drive, just as it does from a Live CD. Ubuntu's casper-rw feature IS ALSO utilized for persistently saving and restoring your changes on subsequent boots."
The part that confuses me is the second statement that the Casper-RW feature is utilized. Isn't that incorrect for the case of a Live Install using their Universal USB Installer? I later discovered that a Persistent Install can be created by downloading and using Version 2.5 of the Linux Live USB Creator. In this case, a second partition is created on the Flash drive for the casper rw feature. Is my understanding correct, or can the Pendrive Linux Universal Installer somehow create a persistent USB drive that will save data and settings?

Does anyone know what happened to the Multiseat feature that had been in the feature list at one point?To briefly summarise, a single machine with multiple graphics cards, sound cards, keyboards & mice provides multiple seats for users. Each user gets their own monitor, keyboard, mouse & perhaps audio. The rest of the machine resources are then shared.
The last I saw on the topic was this discussion, although I have a recollection that there was going to be support in a newer version of X.Org. I've googled around quite a bit, but can't seem to find anything.
Anybody know anything? It would be a great feature to have and it's frustrating to have had such an omission since F8 :-o

I've completed the creation of a Live USB 9.10 install/configuration. I'm booting from a 16GB Flash USB now, with just about everything working, audio, video, wireless, etc. I'd like to remove some of the "live" features of the OS now, to make it more a bootable 9.10 full install. The first step, is to remove the auto-login feature of the live setup. I tried setting a password on the ubuntu user, but it still auto-logins.

I'm about to ditch Freenas as my NAS software and make it an Ubuntu server box. The mainboard is an Asus AT3ION-T dual core Atom board. Freenas runs happily from USB stick. I have no optical device to install Ubuntu from and would like to install Ubuntu Server to a USB stick.

I'm about to install a version of Ubuntu onto a 32GB flash drive, I've downloaded are Universal USB installer that will do most of the work for me, however, it asks
Step 4: Select a persistence option for your USB
and the options are
1GB CASPER -RW
2GB CASPER -RW
3GB CASPER -RW
4GB CASPER -RW
What is persistence? am I better off having more (ie 4GB) since my flash drive is a 32GB drive?

First things first, you will need:1GB or larger flash drive rEFIt (Link at the bottom) A linux installation, virtual machine, or live cdA Mac OS X installation/installation disk Administrator permissions gparted (comes on most linux live cd's) hfsplus/hfsprogs for hfs+ support in linux Alright Step one (in linux):Format your USB key with an MBR partiton table. Add an 8MB ext3 partition named "GRUB" for simplicity. Add a 16MB hfs+ partiton. Use the rest of your disk as FAT32. Step two (also in linux):Mount your ext3 GRUB partiton Open terminal and do "sudo grub-install --root-directory=<mountpoint> /dev/myusb", of couse replacing <mountpoint> with the mount point and myusb with the correct sdX. If you get an error saying that there is no bios boot partition (which you shouldn't), open gparted and select the grub partition and select the flag "bios_grub". Close GParted if it is open and reopen it.
Set the boot flag on the GRUB partition. Copy all of the contents of your live cd iso or cd (including the hidden folder ".disk") to your fat partiton. Skip the following steps in the step two if you don't want persistence In terminal create a zero'd out file called casper-rw in the fat partiton with "dd if=/dev/zero of=/media/LIVE/casper-rw". Replace the /media/LIVE with the mountpoint again.
Now type "mkfs.ext4 /path/to/casper-rw" and follow the instructions if there are any Step three (in mac):Open the rEFIt dmg and copy the "efi" folder to the hfs+ partiton. Locate the file called "enable.sh" in the efi folder Open a terminal and type "sudo " and then the path to the enable.sh. (You can find it by dragging the file into the terminal) Step four:Reboot your computer holding the option key Select rEFIt on your USB drive (If it doesn't appear take it out and plug it back in or boot all the way up and then reboot again) Select "Linux on HD" that has a picture of a flash drive on it. You will now be at the GRUB prompt, so type the following:
Code:
root (hd0,3)
linux /casper/vmlinuz boot=casper persistent
initrd /casper/initrd.lz
boot
Of course take out the persistent part if you didn't use the persistence file. [URL]

i made a persistent Live USB from the Ubuntu Maverick option Startup Disk Creator in the live cd distro. It works really good, i've installed the apps and changes i wanted, but now i'd like to lock persistency so no new changes or any data whatsoever may be stored. Is there a way to disable this capability so it may behave just like the CD adding the changes i made?

I have a USB with two partitions, one FAT32 with Ubuntu 10.04 on it, and one ext4 partition labelled casper-rw. According to the docs this should do to create a persistence installation, but I still get the "can't find persistence medium" error when booting.
Did I do something wrong or is this a bug?
I installed with unetbootin on the FAT32 partition and created the partitions using GParted.

I've tried using usb-creator to create a persistent live USB of Ubuntu 10.04 32-bit, but the program is useless. There's a bug in the program that greys out the options to enable persistence (see here for bug info). I tried workaround #4 listed in that link, but that didn't work either. When I selected another .iso which I moved to the /tmp directory as stated, the "Make Startup Disk" option then became greyed out as well. It'll make a bootable live USB but I need persistence. Is there a good way to do this without using that program And I tried Unetbootin twice, and it wouldn't boot the live system at all. After seeing the Ubuntu splash screen it just stalled at a black screen forever.

I presently have a Karmc LiveUSB with a casper-rw partition, but am thinking of changing the LiveUSB image to Maverick, while still using the existing casper-rw partition and its data (mostly settings for Ubuntu itself, haven't installed any programmes). Using usb-creator, by the way. Are the config files for Karmic and Maverick significantly different that this will cause any major problems? [Separately, I think this will have implications for my existing Karmic install, because I'm planning to clone my Karmic /home partition to a fresh Maverick install.

I've been butting heads with a problem for about a week now. For a while I've been running a DAW (Digital Audio Workstation) off a 4 GB Kingston DataTraveller Flash Drive. Using partimage, I've managed to install this Maverick Ubuntu and load it with Audio Stuff from UbuntuStudio....plus wineasio and some Windohs audio software, then save the images of the partition usb stick (win32 livecd partition and casper-rw persistence partition).I've also done the same thing with a linuxaudio distro called pure:dyne. I restore and use either according to my needs. Obviously 4GB isn't a lot of space....so over the holidays I went out and bought the 8GB version of the DataTraveller. Two weeks later I'm still trying to get things to work right.
The problem is that when I create the casper-rw partition and boot into Ubuntu things slow to a snail's pace. Ubuntu takes over 5 minutes to boot up. Installing anything with Synaptic or whatever takes 5x as long as with the 4GB version of the flash drive. Everything works rather well....although multitasking is laborious, if possible at all. At first I thought it was the usb-key itself. After returning it (twice) I realised this just wasn't the case. 3 different flash drives had performed exactly the same way. Googling around over the last few days I found I'm not the only one to come across this problem...but still no solution.
What makes things weirder is that today I installed pure:dyne on that same stick and it works perfectly...running as smoothly (almost) as from a normal harddrive. Weirder still is the fact that pure:dyne is built from ubuntu itself...the only difference (as far as the whole usb-creation business goes) is that the persistence file/partition is named "live-rw" instead of "casper-rw".
I'd settle for pure:dyne...except it's built on "lucid" not "maverick"....two of my 3 computers have graphics driver issues with pure:dyne and the soundcard support is spotty (which is strange for a distro specialising in audio production) and wine (and therefore vst/i support) is not nearly as good. If anyone has any clue what goes on here I'd be very interested. In the meantime I'll run pure:dyne on the one computer that likes it.

I copy the debian-live-7.6.0-i386-standard.iso to the usb. Now i can live boot into the usb.
I also follow the guide "10.3.1 The persistence.conf file" to make /dev/sda2 my persistence partition. When it boot up and i add the parameter "persistence" it will works. But i want to know how to make it automatically boot with the parameter?
My guess is that i have to make my own live cd then copy to the usb again. If that is it, any tutorial how to make live cd from the live cd i already downloaded?

It only takes a few uses of a LiveUSB drive with a persistence file to fully saturate and generate "0 bytes remaining" messages. When this happens, you can no longer use the drive to install Ubuntu until casper-rw is resized or deleted or the USB device is reformatted. I think persistence shouldn't even be an option and that storing files temporarily in RAM is a better solution.

I am using this image of Debian: [URL]. But it doesn't matter what I do I fail to make it persistent.
I have tried this: [URL] But there is no "grub" on my "install" drive, apparently is an outdated notion.
I have tried this: [URL] (with conflicting info regarding the previous link). By booting with a knoppix USB with gparted. Doesn't matter if I leave the NTFS partition unnamed or call it home_rw, I get no persistence, even writing persistent while booting.
I have tried also changing this (while in knoppix): [URL]. Basically adding the word "persistent" after "live" but it does not work. All changes I make disappear. What it the current way of getting persistence with this package?

I have created a Fedora 15 live usb using LiLi-Usb with a persistence file of 2048mb, on a 4gb flash drive. What I would like to know is two things, will this allow me to update Fedora 15 on the flash drive?, and later, if I chose to install to the hard drive, will the updates cross over?

why another slackish distro? Mine (will be) better than most Please try it before you criticize it It is quite unique in many ways I really did it to show how easily one can make their own 12.2 install into a live distro So, it is a proof-of-concept thing Desktop: My own JWM creation heavily based off Vector's JWM Display manager: Slim from Slackbuilds Packages: All pkg's are 12.2 slack, sbopkg's, and slapt-get/gslapt from Slacky, some others converted from absolute/salixos/source. I custom built the JWM desktop, systray-volume-control, and many from-scratch scripts.
Heres some of the pkg's Games: Xgalaga sbopkg Graphics: Gimp, Imagemagick Office: Abiword, Gaiksaurus, Xcalc Multimedia: Mplayer, XMMS, Audacious, Alsamixergui, Pulsaudio Alsaplayer, Isomaster Misc: Roxterm,rox-filer, PCMANFM, lxterminal, lxtask, leafpad xarchiver, catfish, lxappearance, nitrogen System: Gparted, ddrescue, testdisk, Gnome net tools, WICD wifi-radar, Gslapt, Network: Firefox, dillo, xchat, gftp, grsync

I have an Eee PC with a dead Hdd. I brought it back to life by installing Ubuntu 10.10 on a 16GB SD card. It works 100% but is sluggish.Now I am wondering, from the standpoint of reducing SD card access and writes, would it have been better to create a Live Disc on the SD card with persistence options? What I am thinking is that a Live Disc is designed to run out of RAM, and would thus reduce the activity on the SD card. The only thing this netbook will get used for is the internet. It is a netbook, so the performance is limited, but as far as netbooks go, it is top of the line with dual core and discrete nvidia graphics.

I tried a while getting a live system working with encrypted persistence. The command
Code: Select alllive-persistence activate /dev/sdx2
works perfect, but boot time persistence works only for unencrypted storage. 'Cause I can not append the boot-log as file the most important part here:
Code: Select all+ tailpid=123
+ tail -f boot.log
+ cat /proc/cmdline
+ LIVE_BOOT_CMDLINE=BOOT_IMAGE=/live/vmlinuz boot=live noeject keyboard-layouts=de components persistence persistence-encryption=luks,none initrd=/live/initrd.img debug=true
+ Cmdline_old
+ PERSISTENCE=true
+ export PERSISTENCE
[Code] ....
The most confusing line is "Warning: cryptsetup is unavailable" - I took a look into the scripts, it checks if cryptsetup and askpass is executable if not this message. But:
I mounted the hdd-img file local and took a look: all binaries there.
So I tried a lot getting it working on boot time. I tried it with live-tools from testing, from wheezy and last but not least installed and pinned live-tools to unstable. Always the same. askpass isn't executable on boot time before mounting the persistence.
Config is
Code: Select alllb config noauto
--apt apt
--bootstrap debootstrap
--binary-images iso-hybrid
--distribution testing
--mirror-bootstrap http://ftp.debian.de/debian/
[Code] .....
(tried with binary-images=hdd, too)
and yes, cryptsetup is inside package-list (otherwise live-persistence from within running machine with crypted partitions would not work). Live tools I used for last run is 4.0.3-1 from unstable, before tried with 4.0.2-1 from testing.
Whats going wrong in boot system?

I successfully installed OpenSUSE on a 4gb pen drive using the instructions contained within this portal. However, for the life of me I can't figure out why the persistent feature doesn't work.
Here's my partition table map:
Disk /dev/sda: 80.0 GB, 80026361856 bytes
255 heads, 63 sectors/track, 9729 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes

I want to disable the XF86Search feature in my system. I will try anything.
One of my mouse buttons, when pressed, triggers this XF86Search no matter what I disable or change. (This feature opens up my browser and goes to a search page.) Strangely the mouse button is being interpreted as a key, not a mouse-button press. (This actually may be a bug in Ubuntu...)
How do I disable this feature?
I am running KDE 4.3.5 with Ubuntu 9.10 Karmic (Kubuntu). Though I use BTNX to configure my mouse buttons, this feature has absolutely nothing to do with that. I have tested by disabling BTNX completely and clicking this special button on my mouse still loads a search page.
Here is the xev command output:
Code:
.....
KeymapNotify event, serial 36, synthetic NO, window 0x0,
keys: 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
