Ubuntu Installation :: Persistent USB Usage
May 28, 2010
I would like to know if I can update a live USB version of 10.04I am, unofficially, running ubuntu 10.04 live USB version from a partition on my 250GB USB HDD at work.All the apps I use are web bassed except for zeacom and groupwise which I run from a virtual machine I created using virtualbox ose, this machine is one the network running AD and novel and also MS office and uniflow printing
Everything at the moment is running quite well: I tried this a while ago (9.04 or earlier) but I tried enabling update manager and this killed the boot for my live USB and I don't what to risk toying with a system that is running well but I also want to be up to date.

I've upgraded the generic kernel of my Xubuntu Karmic AMD64 persistent USB installation with the ubuntustudio realtime kernel (2.6.31.9.10). The thing is that the generic kernel is still loading as default and I don't have the option on the boot menu to choose the new one. I don't know how to edit this Grub2 version (grub-pc 1.97 beta 4).I haven't found a GUI package for this either.

I am currently running Windows 7 and would like to "play around" with Linux and learn how to use it, but am not willing to entirely "jump ship: as of yet. Thus, I would like to be able to use my USB key (32 gig) that is persistent. I have had no success in being able to get this to work; I went to http://www.pendrivelinux.com/ and attempted several different times and the only one I could get to work was not persistent.

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.

I am trying to make a usb installed ubuntu(with persistent) unchangeable. The usb needs to use the data from the persistent casper-rw, but in the same time not be able to change the casper-rw. I have tried installing ubuntu on a SD-card, and then simply lock the SD-card. So fine so good, but it just wont bootup then - it says "Aufs mount failed".

I have tried to create a persistent live usb thumb drive using Startup Disk Creator, but have not had any luck. I have tried running Startup Disk Creator from Linux Mint 9 xfce (currently installed on my machine) as well as from live sessions of ubuntu 11.04 Beta1 and xubuntu 11.04 Beta1. When using Startup Disk Creator in Linux Mint, I am able to set the slider to choose how much reserved space I want, but when I reboot, the USB stick does not load, I get an error message about an unknown name in the file. When using the live sessions of ubuntu or xubuntu, the section with the slider to choose how much of the usb stick to devote to the persistence file is greyed out. I get the same result whether I choose the xubuntu iso or the ubuntu iso as the source disc image. I have used the same USB stick and Startup Disk Creator to make persistent live installs before - is there something about 11.04 that does not allow persistence?

I am a linux newbie and want to try to run Fedora 13 from a 4Gb USB flash drive for a while until I decide to do a permanent install.My problem is that although I selected to create persistent storage using the liveusb creator, nothing is being saved after rebooting.For reference, I downloaded the 64bit version using bittorrent, and I created the live usb on windows 7.Is there some setting I must set to enable persistent storage?

I want to create a combined portable Ubuntu / USB stick.For this I intend to install Ubuntu to my 16 GB USB Drive. I am going to install some rather big programs (Matlab, Maple...) and therefor, I think the 4 GB persistent space in different startup-USB creators are to small.Because of this, I want to install Ubuntu to the USB drive, to get full functionallity. Also because of the small USB Drive size, I dont want to create two different partitions. For USB Drive use, I want to be able to save files larger then 4 GB (ie. not FAT32).
How can I create a fully functional Ubuntu USB, that can also be accessed from Windows? I understand that NTFS and Ubuntu is a bad mix, FAT32 have file size restrictions, and Windows cant accesss ext3/4.I saw someone talk about installing Ubuntu using the 'install in windows' to bypass Ubuntu-NTFS problems, but the link was broken, and I could not see how it was done. Also this [URL] talked about making the home folder accessible, but the linked site is now down.

I have a persistent pendrive of Ubuntu: [URL]
It has a file where it saves the configuration of my computer: casper-rw
But if I boot this USB flash drive in another computer I would like to do it in a fresh way, that is, without loading the configuration of my computer (saved in the casper-rw file). For example, in Puppy Linux this can be done easily, just putting pfix=ram in a boot option of syslinux.cfg and selecting this option when booting.
I think this is important because I think that otherwise the Ubuntu (at least in some cases) cannot open if used in a computer different to the one where casper-rw was configured. It happens to me that I cannot run Ubuntu with my pendrive when inserted in a different computer (I think the reason is what I've said).

After setting up a persistent Lubuntu (10.10) on a 4GB SD with Universal-USB-Installer-1.8.1.8 , I started changing the passwd of the original user ubuntu , but after rebooting, I can't log in. So I resorted to hitting Ctrl+the function key that gives you a CLI, and changed the password for "ubuntu" user then tried to log on again. No success.Then I created a new user with a password, and managed to log in with this user, but it is not the same experience, the menus are lacking, and it is not possible to log on to wifi, similar problem to this user

I can boot from USB because when i use Unetbootin everything works fine. Although it'snot persistent in that situation. I seachered the web but i can't find the solution. I have run a script which i ran into on Sourceforge.net. The results are in the attachement. But unfortunately i am real Newbie on linux so..

I was wondering if it can be possible to boot debian from micro sd card and have it persistent. I have checked the bios of my laptop and there are options to boot from USB and HDD (and from floppy, cd, network and hard disk), but not from sd card. Would it be a problem or could there be workarounds. That is of course if the whole thing is a good idea at all.
I have already booted the laptop from USB, but I would like to use it for everyday work and USB sticking out is bound to get snapped off. Sd card on the other hand would go inside in the slot. The hard disk is dead and is a bit expensive to replace (and unnecessary in respect of the volume, I only need a couple of gb for work)

So i installed debian squeeze in virtualbox with xfce and i thought that it was persistent. when i powered down the virtual machine and started it up again later I only had the option of installing it again. Do i use save state to keep it in the installed stage? would i have to do that each time i made a change? i want to make sure so that i don't keep having to re install it.

I'm trying to create a persistent live Jessie system on my 8GB USB drive.
If that matters, I'm currently on an Arch Linux system, and I partly followed what's on the relative wiki (Pages Create a new MBR for a USB stick, Manually create a USB flash installation and Install Syslinux), plus a CrunchBang post explaining how to make a persistent live USB out of any Jessie-deriving distro (like their BunsenLabs Hydrogen).
The problem is, even if Debian boots up more than fine, the system isn't persistent at all.
Here's what I did (I know some passages are redundant, but still...):
Downloaded the Cinnamon flavor of Jessie via torrentErased the old MBR
Code: Select all# dd if=/dev/zero of=/dev/sdb bs=512 count=1 && syncCreated a 1.1G W95 FAT32 (LBA) active partition and used the remaining space on a Linux partitionFormatted the first to FAT32 and labelled it "Debian64". Formatted the second to ext4 and labelled it "persistence"
Code: Select all# mkfs.vfat -n Debian64 /dev/sdb1
# mkfs.ext4 /dev/sdb2 -L persistence
Mounted the first partition and the iso

I've created live squeeze usb-hdd and if I boot first time the udev system writes the MAC address of the network interfaces into /etc/udev/rules.d/70-persistent-net.rules.Because I use full persistence, the file is there on the next boot and I don't get network running automatically on other computers. My problem is, howto remove 70-persistent-net.rules every time during the startup?

I'm running into a problem where my system is running out of disk space on the root partition, but I can't figure out where the runaway usage is. I've had a stable system for a couple of years now, and it just ran out of space. I cleaned some files up to get the system workable again, but can't find the big usage area, and I'm getting conflicting results.For example, when I do a df it says I'm using 44GB out of 58 GB:
Code:
[root@Zion ~]# df -h
Filesystem Size Used Avail Use% Mounted on

I recently upgraded two of my computers from 9.4 to 9.10. They are: HP Pavilion a510n (Desktop) Gateway T-1620 (Laptop)
Both are having the same problem. They are running at constant 100% CPU usage. when I look into the task manager there is no apparent cause. all active processes add up to at most 25%. On the desktop its just noisy cause the fan is always running at full blast. on the laptop however, it causes it to auto shutdown after 15 minutes or so due to overheating.
Im concerned that this is going to cause long term damage to my machines.

well I went to wubi-installer, and installed Ubuntu, and I love it, I don't want to go back to windows 7, but anyways, I set Ubuntu to my D: Drive, (200GB Space) and I installed Steam (Steampowered.com) to get my games on Ubuntu. I installed all of my games, but here is a big problem, I can't figure out how to use more than 30GB on Ubuntu, it just doesn't work. I got GParted, and the D: drive is set to 195 GB (200, but Ubuntu used 5GB)

I've come across a really strange issue with one of my RHEL servers. The "free" command shows that 7019 MB of memory are actually in use by my system, but when summing up the actual usage (or even virtual usage like the example below) it doesn't add up - the sum is far less than what is reported by "free":
Code:
[root@server1 ~]# free -m
total used free shared buffers cached
Mem: 12011 7946 4065 0 4 23
-/+ buffers/cache: 7919 4092
