I've added this script mostly as-is to the bootstrap.git tree as build-rootfs-img.sh. Note that I took out the mkdirs and mknods in what I checked in; those are being handled in the script init-rootfs.sh which is now being run by the stage1 script when it completes everything it needs to start stage2. Thanks, John. I've already used it a couple of times :). -- ciao, al ----------------------------------- Al Stone Software Engineer Red Hat, Inc. ahs3@xxxxxxxxxx ----------------------------------- _______________________________________________ arm mailing list arm@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/arm
