Overall, I have a few comments. 1. Splitting ovs-vswitchd and ovsdb-server into separate packages will need rock solid testing to figure out any upgrade or downgrade issues. Those 2 have been together for a long time and it will have to be done very carefully. 2. I am not a big fan of splitting ovn-central into 3 separate packages (one for ovn-northd, one for NB DB and one for SB DB). Specially because, we are anyway dependent on a config file to figure out who/where to connect to. I think, having the single package is easier for people to get started and explore OVN. Advanced users, will anyway have to use configuration scripts, so as well use that to decide the daemons to start. > > Andy Zhou (5): > rpms: Seperate ovsdb-server into its own package > rpms: Style fixes > rhel: Rename nrothd to central service > ovn-ctl: Factor out start/stop ovnsb/ovnnb > rpms: Adding three additional OVN packages > > ovn/utilities/ovn-ctl | 55 +++++++- > ovn/utilities/ovn-ctl.8.xml | 4 + > rhel/automake.mk | 3 + > rhel/openvswitch-fedora.spec.in | 141 > +++++++++++++++------ > rhel/usr_lib_systemd_system_ovn-central.service | 34 +++++ > ...sr_lib_systemd_system_ovn-northbound-db.service | 16 +++ > rhel/usr_lib_systemd_system_ovn-northd.service | 29 ++++- > ...sr_lib_systemd_system_ovn-southbound-db.service | 16 +++ > 8 files changed, 251 insertions(+), 47 deletions(-) > create mode 100644 rhel/usr_lib_systemd_system_ovn-central.service > create mode 100644 rhel/usr_lib_systemd_system_ovn-northbound-db.service > create mode 100644 rhel/usr_lib_systemd_system_ovn-southbound-db.service > > -- > 1.8.3.1 > > _______________________________________________ > dev mailing list > [email protected] > https://mail.openvswitch.org/mailman/listinfo/ovs-dev > _______________________________________________ dev mailing list [email protected] https://mail.openvswitch.org/mailman/listinfo/ovs-dev
