Well as maintainer of systemd-rpm-macros and for the reasons given above, we want to get rid of DISABLE_RESTART_ON_UPDATE. There were already some discussion about this subject that happened on @systemd-maintainers mailing list. Could you give me the status of openvswitch ? Does it still use DISABLE_RESTART_ON_UPDATE ? if so why exactly and how a sysadmin is supposed to use it ? by globally disable the restart of all packages ?
