# mk-rescueimage.ia64 - builds a rescue image from an existing tree
#                       which can be converted into a isolinux bootable
#                       iso and used as a sysadmin rescue image.
#
#
# Usage: mk-rescueimage.ia64 <src-tree> <dest-dir> <productname>
#
# the rescue image will be created as <dest-dir>/ia64-rescueimage
