General :: Ubuntu Live-cd Persistent And Also Read-only?
Mar 18, 2010
I have already a ubuntu live-cd running with persistency on a USB stick but I would also want to be able to launch it, loading all the saved preferences in the casper-rw partition, but without any modifications on those settings.The idea is to have on the start menu 2 options:1- start ubuntu saving changes (on the persistent partition)2- start ubuntu not saving changes (not persistent, but loading the previously changed settings)This way, I could save preferences incrementaly, but only when I opted for the option 1.
I have made a persistent live usb of suse 11.2 using a '.iso' file. Now when I boot from the Live usb, the file system appears read only. I want do some modifications in the files.
I have an old EeePC 701 4G netbook that I'm about to reconfigure for a friend who needs it to read PDF files, surf the net occasionally and do few other things. I'm going to install Ubuntu Netbook Remix, version 10.4.
Now, the 701 only has four gigabytes of internal storage, and I'm unwilling to spend money on it to expand its memory. When installed UNR takes up about 2.3 gigabytes, which leaves a bit more than a gig available for user data, and that's not much at all.
However, I could copy the live files off the memory stick in the main drive and use the remaining space for a casper-rw partition. Then it'd be only a matter of editing the bootloader in order to have a system that saves changes. This way I could fit the system on only 700 megabytes.
My question is: is there any drawback to running a persistent live off the main drive as the operating system? Something that would make me prefer eating up two thirds of the drive with the system, rather than just a fifth of it?
I imagine upgrades would eventually take up a lot of space, as they'd essentially copy a lot of the system in the live partition, but this is easily solvable by not performing them. I don't think the intended user would miss them, since she'll only really need three or four apps.
I have a 16Gig usb drive and i've managed to get Backtrack up and running on it with persistence, but I really want to have on it is Mint, Backtrack 5, if possible Ubuntu and hirens bootcd. I don't really want to use unetbootin. how i need to set up the partitions, if it's possible to have both Backtrack 5 and Ubuntu with persistence since they both use casper-rw and what mint needs for persistence.
I'm attempting to create a persistent live USB. My flash drive is 32 GB, so I plan on creating a 8 or 16 GB ext casper-rw partition for my persistence (as described here.) I would like to have the remainder of the space available as an NTFS partition. However, most of what I'm reading indicates that only FAT32 is possible for a bootable Ubuntu USB.
I've been told that if I simply installed to USB drive as if it were a regular old HDD, it would be bootable and I could simply format the rest as NTFS. I'm wondering if this is true and why all these utilities I've found (Linux Live USB Creator, Universal USB Installer, etc...) insist on FAT32. Persistent (>4GB) bootable usb, with the rest of it a windows-recognizable NTFS partition?
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?
Currently got a 32bit laptop and im running Ubuntu desktop 10.10 with the 32 bit version, If I upgrading my machine would i need to make a new persistent live usb for the 64 bit machine?
I am running a live (4gb) USB of Fedora_14 with 768mb persistent storage. I am trying to add firmware for broadcom wireless link, as it is not natively supported. When I download tar, extract and copy missing firmware then reboot... all changes are reverted back. How do I make these changes persistent upon reboot.
I'd like to make a "live" USB, probably Ubuntu or a derivative such as Mint. How do I make it persistent? FWIW, this particular project will be primarily used for Ubuntu Studio. My hardware works fine with all versions of Ubu and Deb so there are no driver issues, simply the question of adding persistence to the stick
I partitioned a 32 gB flash drive to one 8 gig and one 24 gig partition. Both fat32. I wanted to be able to access the 24 gig partition from XP.I installed a persistent 10.04 on the 8 gig partition.All ran well for about 3 weeks. Today during boot up I noticed that it had stalled at "creating live session user". I left it there for several minutes and then powered down to retry.Several attempts to boot left me at the same spot.I looked at the boot up messages and noticed this error... "unable to find persistent home media".I don't have a ton of save info on the live user account but I would like to be able to fix this type of problem.
I need to have a persistent Debian install on a thumbdrive to run a computer that is currently diskless (dead hard drive). So far I've managed to get it to boot Squeeze live beta by setting up the thumbdrive with UNetBootin, but it's not persistent. I found this, but step 6 is a mystery to me, as I can find no such command or package.
I've created a live and persistent USB boot of OpenSUSE 11.2 KDE according to the howto. It boots and works fine for about 5 minutes and then hangs. Only the mouse will move but I can't click on anything and it never comes back.
I just tried Centos 5.2 Live starting from a 2 GB USB flash drive. Everything seems to run fine, fast, stable - except for that the persistent feature is not working. I created the USB from Windows using the Centos 5.2 LiveCD image and the current version of Live USB Creator (3.7), and declared a 256 MB persistent space.
This persistence feature had worked before with Fedora 11 but the system resulted unstable, kernel panic.... Now Centos has been solid for hours in a row... but the file where persistence should be reflected remains untouched with the initial creation timestamp. When rebooting, every change in config, file created etc gets lost.
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).
Yesterday I did follow exactly the description how to build a live system on a USB Stick with the additional second partition for the data of Live_USB_stick. So far I had success, as my Netbook did start booting and loaded the OpenSUSE 11.2. Then I rebooted the Netbook and it never again comes up with the 11.2. It looks as if it would stop somewhere at starting the graphical system, but I'm not sure.
Today, second try, I created the USB stick with the 11.2 Live System only (no second partition). My Netbook starts booting and shows the 11.2 system successfully, also further boots are the same successful. Then having created the Live system with the second partition again, results in a un-bootable Netbook again (not even the first time it comes up).
What I wonder when I did check the USB partitions: the one (sdg1) with the Live-CD can be mounted and the content is readable. The second one (sdg2) cannot be mounted; shouldn't it be mountable and shouldn't it be formated with a file system? Did anyone have some experience on this? Or, at least, the people having a running persistent live system, what does the partition them show up?
I just set-up my fedora-14 live usb on an 8gb usb hard drive but I see the space left on '/' is less than 800mb (I created a 3.5gb persistent file) like so: Code: livecd-iso-to-disk --unencrypted-home --home-size-mb 3500 --overlay-size-mb 3500 Fedora-14-x84_64-Live-Desktop.iso /dev/sdc1 but I still don't have much space to install programs.
Is there a way to trick yum into installing programs under /home/liveuser/programs instead ?: Code: [liveuser@localhost ~]$ df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/live-rw 3.0G 2.8G 223M 93% / tmpfs 1002M 352K 1002M 1% /dev/shm /dev/sdb1 7.4G 2.0G 5.1G 28% /mnt/live /dev/loop5 3.2G 130M 2.9G 5% /home varcacheyum 1002M 0 1002M 0% /var/cache/yum /tmp 1002M 92K 1002M 1% /tmp vartmp 1002M 0 1002M 0% /var/tmp
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 want to customise an amnesic Debian environment (like Kali Live CD) with everything (Users, background, icons, etc.) set up to work the way I need. This OS should be inside a memory stick, and, most important, it has to have an encrypted partition I can mount and unmount whenever I want to save persistent data.
I have Lenny installed. How to create, using live-helper customized Live USB with a persistent /home partition on this USB stick, to save changes between boots?
live usb media does not let me to to save files and make modifications to live operating system that will persist after a reboot
I made the bootable stick with the liveusb creator at https://fedorahosted.org/liveusb-creator/ using an iso image of f10 live cd, a flash drive with 2 Gb capacity and a paersistent storage setting of 200 Mb
I changed root=XXXXXXXXXXXXXXi-do-not-remember-XXXXXXXXXXXX to
On the flash drive to make it bootable
I installed gparted on live operating system and when i rebooted gparted was not installed.
When i boot from live USB, i can't write anything to it, because the 'Filesystem is read-only'. How can the boot USB be mounted as read-write? Maybe some boot options are needed?
I want to install 11.04 next to my working 10.04 system. First I need to make room for the new system so I have booted from a live cd and started GParted. In GParted the partition with the 10.04 system on it, /dev/sda1, has a red circle with an exclamation mark in it and I cannot resize it. When I doubleclick on /dev/sda1 there is the following warning
Quote:
Failed to change to directory '.'(Stale NFS file handle) Failed to change to directory '.'(Stale NFS file handle) Unable to read the contents of this file system! Because of this some operations may be unavailable.
The following list of software packages is required for ext4 file system support: e2fsprogs v1.41+.
The 10.04 system is working and has worked like a dream for a couple of years and the machine has never had any other system on it. Why would the live CD not be able to read ext4 fs?
Os version: fedora 12 (x86)I wanted to resize my root partition so i read from internet that using gparted through live cd could do it, so i did the same. However after rebooting, i once again came across the screen i hate the most:(the black screen with grub prompt): grub> i don't know if there is still a way to recover my previous installation. also tell which is the best and most reliable way to resize ext4 root partition so that i do not make the same mistake in future.
today I setup a USB drive to use Qemu to boot Backtrack. It was so easy my grandma could do this! My thanks goes out to anyone who worked on the Qemu project!Now, I am wondering, how hard it is to get a distro to run persistently, using Qemu. I would like to have my .bashrc, apps I install, small scripts I write, etc. saved instead of the default bootup each time.
It doesn't matter which distro it is as long as it is Debian based. I did find this thread which I will try later but it sounds almost like I need to boot from USB first... not quite sure. I was hoping I could get further insight from someone before I waist too much time working toward something that will not happen.
I want my samba to keep my windows attributes exactly what the user setted in windows I mean if it has read only file in win box and copy it to samba share ,samba keep it read only and same for other attributes but it does not do it now with my configuration:Quote:

I installed Slitaz on my USB. However I can't figure out how to make it persistent automatically. There are different sources telling me different ways to make it persistent.
One told me to add "slitaz home=usb" to the syslinux.cfg file like this:
http://www.slitaz.org/en/doc/handbook/liveusb.html gave an example of how to do it manually but I didn't try it and I also want it to happen automatically.
custompc.co.uk/features/602451/make-any-pc-your-own-with-linux-on-a-usb-key.html is an older article that also explains how to make the USB persistent but I don't want to try it cause it looks outdated (from 2008)
does anyone know the best way to make the USB automatically persistent?
I am trying to install Linux (the distros I have attempted it with are Arch, Fedora, Ubuntu and Mint) on a USB drive and make it work like a removable hard drive, keeping programs and settings. I tried it manually at first, partitioning the drive with Fedora's "Disk Utility" and dd'ing a Fedora 13 iso over. I should note here that I have definitely configured the BIOS correctly, enabled booting from removable media and set it as the default with all other devices disabled, but that I have never actually booted from USB before with this motherboard. On bootup I got
Code:
DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER
I then tried it with Ubuntu 10 and Ubuntu's "usb-creator". This was apparently successful, but on bootup I got:
Code:
missing operating system
DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER
I downloaded UNetBootIn, but the application kept saying I needed "p7zip-full", which I couldn't find anywhere. I then got Fedora liveusb-creator, but whichever iso I give it I get this error:
Code:
Unable to find LiveOS on ISO I looked at the source code and it seems to be looking for a directory named LiveOS on the iso containing the files "squashfs.img" and "osmin.img" Here is the code (usr/lib/python2.6/site-packages/liveusb/creator.py, line 575):
Code:
def extract_iso(self): """ Extract self.iso to self.dest """ self.log.info(_("Extracting live image to USB device..."))
[code]...
I couldn't find much about what LiveOS actually means and why I need it to create a bootable USB, so if anyone could tell me more about this that would be great. Is this (the .img files) the only thing distinguishing a "Live" OS from a non-Live one? I looked in my Ubuntu live CD and there was no such directory, but it works perfectly well. In case it would make a difference, the stick is 8GB and branded duracell, not sure what manufacturer it is.
I have followed the link:http://www.ejabberd.im/muckl and setup ejabberd. I installed muckl too. I can see http://<ip>/muckl running well.But the Issue is I am unable to create Rooms.Any one who have hands on this?
