update_tasks:
# With the layered product packaging, the key package is rhosp-openvswitch. It depends on
# a openvswitch package that includes the version as part of the name (e.g openvswitch2.10).
# This requires some additional special handling:
# - During an upgrade the package name for openvswitch may change so
# upgrading the currently installed package won't do anything.
# - The rhosp-openvswitch package "obsoletes" several packages,
# including older openvswitch packages. This results in a pretty
# severe uninstall/install sequence of operations that stops and
# removes openvswitch which could break network links required to
# continue the upgrade.
# - To prevent rhosp-openvswitch breaking connectivity, the currently
# installed core openvswitch packages need to be erased from the rpm
# database but leave the binaries intact. This effectively
# short-circuits the obsoletes mechanism in rhosp-openvswitch and
# leaves the core elements of openvswitch running. In the future we
# may replace this mechanism with "an upgrade on reboot". We only
# do this for the core openvswitch packages so other packages
# obsoleted by rhosp-openvswitch will be removed when
# rhosp-openvswitch is installed/upgraded.
# - Neither the rhosp-openvswitch nor openvswitch{m.n} package enables
# or starts the systemd service so there must always be a task
# to ensure that it is enabled or OpenvSwitch functionality won't be
# available on reboot.
# - With LP, we expect that the core openvswitch package name will
# change with every major upgrade so this special handling will
# eventually replace the special handling of upgrading the
# openvswitch package "in place"
