I created with liveusb-creator a 4GB USB with persistence 2400 of iso soas--------328; using a usb 500GB HD install of f13 Beta1 Gnome + sugar rebooted with the new USB in sugar terminal: su - yum install wget gedit wget <a class="moz-txt-link-freetext" href="http://(path">http://(path</a> to soas nightly composes/soas/......328 (loaded in /home/liveuser/) opened with gedit <a class="moz-txt-link-rfc2396E" href="mailto:soas@lists.sugarlabs.org">"soas@lists.sugarlabs.org"</a> from a 2nd USB in sugar frame saved it in /home/liveuser/ chmod 077 modified_livecd-iso-to-disk script If I do a "ls" I see both in /home/liveuser then I get lost on how to use your script I tried in root: /home/liveuser/ modified_livecd-iso-to-disk --noverify --delete-home --extra-kernel-args selinux=0 --copy-overlay /dev/live /devsde1 new target usb is /dev/sde1 formatted ext3 with boot flag  I got this error msg mount: wrong fs type, bad option, bad superblock on /dev/loo5, missing codepage, or helper program, or other error Cleaning up to exit... Any help would be appreciated Do I have to use your script to create the USB? vs using graphical liveusb-creator to make this work?

You'll need two USB keys for this. (1) use Fedora's LiveUSB Creator to prepare the first key with SoaS (2) boot the first key and apply some changes as in:        (a) change the language        (b) download a number of activities (3) plug in the second USB key and determine its mount point (4) run as root on the first key: yum install livecd-tools (might or might not be already present, depending on which SoaS version you use) (5) execute the following command from the terminal on the first key:        livecd-iso-to-disk --overlay-size-mb 300 /dev/sr0 /dev/sdc1 (in which case /dev/sdc1 would be the mount point of the second key) Does this [ ] WORK or [ ] FAIL?

In Fedora13 (32-bit), ran this script:     modified_livecd-iso-to-disk --overlay-size-mb 400 --delete-home --extra-kernel-args selinux=0 /path_to_soas-i386-20100327.19.iso /dev/sdb1 3. Booted the LiveUSB device1 and made a few changes. 4. Mounted a second USB device2 on an extended USB port on my monitor, confirmed its partition name as /dev/sdc1, then unmounted it. 5. Mounted my Fedora13 partition (/dev/sda1) onto the device1 LiveUSB image, and ran this script in the Sugar Terminal:    /mnt/F13/home/account/.../ modified_livecd-iso-to-disk --noverify --delete-home --extra-kernel-args selinux=0 --copy-overlay /dev/live /dev/sdc1 6. Shutdown and swapped USB devices in order to boot device2 from the motherboard USB port. 7. Confirmed that I had a replicated image with the copied overlay file. 8. More testing needed.

(I'm not familiar with the sources for the configuration files, so there may be some better way to address this.) This script allows one to use the optional installation parameters of livecd-iso-to-disk to customize the new installation structure. I have examined or tested all the possible code paths, so close examination and testing is needed before it could be accepted upstream. Note, there is a --skipcompress option that might be of interest to those who would rather have a full ext23 embedded on the LiveUSB. The relavent code is here: if [ -n "$skipcompress" -a -f $CDMNT/LiveOS/squashfs.img ]; then mount -o loop $CDMNT/LiveOS/squashfs.img $CDMNT || exitclean cp $CDMNT/LiveOS/ext3fs.img $USBMNT/$LIVEOS/ext3fs.img || (umount $CDMNT ; exitclean) umount $CDMNT elif [ -f $CDMNT/LiveOS/squashfs.img ]; then cp $CDMNT/LiveOS/squashfs.img $USBMNT/$LIVEOS/squashfs.img || exitclean elif [ -f $CDMNT/LiveOS/ext3fs.img ]; then cp $CDMNT/LiveOS/ext3fs.img $USBMNT/$LIVEOS/ext3fs.img || exitclean fi More work is needed to protect the /home/liveuser/.sugar/default/owner.key files from the copy. Hope this helps advance the easy customization and replication of LiveUSB images. --Fred </pre> <pre wrap=""> <hr size="4" width="90%"> _______________________________________________ SoaS mailing list <a class="moz-txt-link-abbreviated" href="mailto:SoaS@lists.sugarlabs.org">SoaS@lists.sugarlabs.org</a> <a class="moz-txt-link-freetext" href="http://lists.sugarlabs.org/listinfo/soas">http://lists.sugarlabs.org/listinfo/soas</a> </pre> </blockquote> </body> </html>
