# Factory install images operate by downloading content from a
# server.  In some cases, the downloaded content contains programs
# to be executed.  The downloaded programs may not be complete;
# they could have dependencies on shared libraries or commands
# that must be present in the factory install image.
#
# PROVIDED_DEPEND captures a minimal set of packages promised to be
# provided for use by any downloaded program.  The list must contain
# any package depended on by any downloaded program.
#
# Currently, the only downloaded program is the firmware installer;
# the dependencies below are gleaned from eclass/cros-firmware.eclass.
# Changes in that eclass must be reflected here.

# COMMON_DEPEND tracks dependencies common to both DEPEND and
# RDEPEND.
#
# For chromeos-init there's a runtime dependency because the factory
# jobs depend on upstart jobs in that package.  There's a build-time
# dependency because pkg_postinst in this ebuild edits specifc jobs
# in that package.
