Not useful. The layperson would require training in http://wiki.laptop.org/go/Ok and use of USB drives, and then once the image is obtained they would need to be shown how to run zhashfs in olpc-os-builder. We do not have a program available at the moment for the reverse of fs-copy, that is, reading an image from USB drive and writing it to internal storage. It would take about 15 minutes to run, as opposed to the usual 5 minutes for fs-update. This would not be a difficult program to write, estimated four hours effort. But I don't think we have a need for it at the moment, and our deployment support team does not wish to encourage imaging. I'd have to get some buy-in. Both steps could be wrapped in a boot script to avoid typing by the layperson. > Is this a replacement for http://wiki.laptop.org/go/Imaging_for_XO-1.5 ? No, not entirely.

Jerry could also write a startup script that does these actions if the serial number changes since last boot. But that would have an unpleasant side-effect of losing all saved data if either (a) the serial number can't be read, or (b) the internal microSD card is moved to another unit as part of a repair. Making /home/olpc a symlink to /home/$SERIAL_NUMBER might be useful. -- James Cameron http://quozl.linux.org.au/ _______________________________________________ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
