#
# Install a bunch of packages using rpm.
# There are two solutions in an image's FRESH generation:
# 1) main package solution
# 2) complementary solution
#
# It is different when incremental image generation is enabled:
# 1) The incremental image generation takes action during the main package
#    installation, the previous installed complementary packages would
#    usually be removed here, and the new complementary ones would be
#    installed in the next step.
# 2) The complementary would always be installed since it is
#    generated based on the first step's image.
#
# the following shell variables needs to be set before calling this func:
# INSTALL_ROOTFS_RPM - install root dir
# INSTALL_PLATFORM_RPM - main platform
# INSTALL_PLATFORM_EXTRA_RPM - extra platform
# INSTALL_PACKAGES_RPM - packages to be installed
# INSTALL_PACKAGES_ATTEMPTONLY_RPM - packages attemped to be installed only
# INSTALL_PACKAGES_LINGUAS_RPM - additional packages for uclibc
# INSTALL_PROVIDENAME_RPM - content for provide name
# INSTALL_TASK_RPM - task name
# INSTALL_COMPLEMENTARY_RPM - 1 to enable complementary package install mode
