    Question Startup disk creator 4 GB + Partition support

    Add support to Startup disk creator to create 4 GB + Casper-RW Partitions.

    An option in Startup Disk Creator to create casper-rw file or Casper-rw partion size above 4 GB in size.

    Since now a days we find pen drives in big sizes.

    What are your views?
    I may link this thread to brainstorm later.....

    Yes, that would be very useful.

    I don't know why the limit is at 4GB right now. Maybe it has to do that the stick is formatted with FAT (right?), which has a max file size?

    Anyway: any solution that would make bigger sticks fully usable would be great.

    The max file size on FAT32 volumes is 2^32 - 1 bytes (4 GiB), and since the casper-rw is just a loopback filesystem, it is constrained by the file size limits of FAT32.

    https://wiki.ubuntu.com/LiveUsbPendrivePersistent/ describes how to instead create an ext3/ext4 casper-rw partition, if you have a USB stick larger than 4GB.

    I had got this idea from TAILS. One of TOR Projects.

    It has a build in 'Tails USB installer' which installs Tails to an empty USB drive and re-partitioning it creating an encrypted persistent partition.

    See : https://tails.boum.org/doc/first_ste.../index.en.html

    I do NOT want the persistence file to default to ON . It should be an option that you have to enable not the other way around.
    if it ain't broke you haven't tweaked it enough

    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 add "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.

    Follow the above but do not edit text.cfg.
    When booting press F6 and type <space>persistent to get a persistent session.
