Usage: ${0##*/} [ options ] tarfile bucket [arch]
register a UEC tarball (ie, per http://cloud-images.ubuntu.com)
if arch is not provided, a name-based attempt is made to guess
tarfile may be a url
options:
--hook-img e invoke 'e' with full path to downloaded disk image
-k | --kernel k use previously registered kernel with id 'k'
specify 'none' for no kernel
-K | --kernel-file f bundle, upload, use file 'f' as kernel
--rename-kernel k rename kernel to 'k' (applies to loader)
-r | --ramdisk r use previously registered ramdisk with id 'r'
specify 'none' for no ramdisk
-R | --ramdisk-file f bundle, upload, use file 'f' as ramdisk
--rename-ramdisk r rename ramdisk to 'r'
--resize s resize the partition image before uploading
's' must be valid input to cloud-resize-image
--save-downloaded if the image is a url, save it to '.'
-q | --quiet be quiet, only output published ids
-l | --use-loader use the loader kernel rather than linux kernel
--rename-image f rename image to 'f' before publishing
Example:
- ${0##*/} lucid-cloud-i386.tar.gz my-lucid-bucket i386
