# Create a xenguest base image
#
# This recipe creates a base image that is then extended by other recipes
# through xenguest-image class.
# xenguest image type is using this as base to add a kernel and a disk image
# to create a guest
#
# The recipe is also adding files in those directories to the xenguest image:
# - ${WORKDIR}/extend/disk-files: all files in this directory will be added to
# the guest disk files (using --disk-add-file)
# - ${WORKDIR}/extend/files: all files in this directory will be added to the
# guest xen files (using --xen-add-file)
# - ${WORKDIR}/extend/guest.d: all files in this directory will be added to
# the xen append configuration files (using --xen-append)
# - ${WORKDIR}/extend/init.[pre|post|d]: all files in those directories will
# be added to the corresponding init scripts (using --init-[pre|post|script])
# You can bbappend this recipe and put files in ${WORKDIR}/extend to add
# elements to the image.
