Hi Numan, Han,
A quick remind. Do you think such change is okay?

Hi,
Sorry for the long reply. There were long NY holidays in Russia.
I do have same thoughts as Han.
Maybe, it's better to introduce separate option --ovn-manage-ic-ovsdb,
which can have NO as default value and then just pass --ovn-manage-ic-ovsdb=yes
in ovn-ic system-unit?
In such situation current behavior for direct ovn-ctl start_ic call would
not be changed and at the same time ovn-ic systemd unit will behave similar to
ovn-northd: it will start all necessary services for ovn-ic by invoking:
`ovn_ctl start_ic --ovn-manage-ic-ovsdb=yes $OPTS` inside system-unit.
Does that look better?
If yes, I'll update PR.
Regards,
Vladislav Odintsov

Thanks Han. I will let Vladislav comment on this.
I submitted this patch from the PR -
