From: Numan Siddique <nusiddiq@redhat.com>

Until now, OVN uses the openvswitch rundirs (rundir, logdir, etcdir).
The commit [1] changed the package name from openvswitch to ovn, but
it didn't take into the account the effects of it. When "make install"
is run ovn-ctl utility is copied to /usr/local/share/ovn/scripts folder.
ovn-ctl depends on 'ovs-lib' and it is not present in this scripts foler.
Because of which we cannot start OVN services using ovn-ctl.

This patch addresses all these issues. It changes the rundir to
ovn specific ones. (i.e /usr/local/var/run/ovn, /usr/local/var/log/ovn,
/usr/local/etc/ovn with default configuration).

[1] - 7795e0e28dce("Change the package name from openvswitch to ovn in AC_INIT()")

Bleep bloop.  Greetings Numan Siddique, I am a robot and I have tried out your patch.
Thanks for your contribution.

I encountered some error that I wasn't expecting.  See the details below.

Hi Numan,

I tried out your patch. Compiling, check, install worked fine:

./boot.sh
./configure --prefix=/home/dceara/local-builds/usr
--localstatedir=/home/dceara/local-builds/var
--sysconfdir=/home/dceara/local-builds/etc CFLAGS="-g" --enable-Werror
--enable-sparse
make -j8 check-am TESTSUITEFLAGS="-j8"
make install

While running OVN I noticed the following:
a. if we don't export the path to ovn-ctl and ovs-ctl and try to run
the scripts from their path we get:

$ cd /home/dceara/local-builds/usr/share/ovn/scripts/
$ /home/dceara/local-builds/usr/share/openvswitch/scripts/ovs-ctl
start --system-id=local && ./ovn-ctl start_nb_ovsdb && ./ovn-ctl
start_sb_ovsdb && ./ovn-ctl start_northd && ./ovn-ctl start_controller
Starting ovsdb-server                                      [  OK  ]
Configuring Open vSwitch system IDs                        [  OK  ]
Starting ovs-vswitchd                                      [  OK  ]
Enabling remote OVSDB managers                             [  OK  ]
./ovn-ctl: line 23: ./openvswitch/scripts/ovs-lib: No such file or directory

This happens because of the change in ovn-ctl to determine $ovsdir.
But I guess that's not a big issue as it's not really expected for a
user to run it like that, right?
If I use the full path it works fine:

$ /home/dceara/local-builds/usr/share/openvswitch/scripts/ovs-ctl
start --system-id=local && $PWD/ovn-ctl start_nb_ovsdb && $PWD/ovn-ctl
start_sb_ovsdb && $PWD/ovn-ctl start_northd && $PWD/ovn-ctl
start_controller
Starting ovsdb-server                                      [  OK  ]
Configuring Open vSwitch system IDs                        [  OK  ]
Starting ovs-vswitchd                                      [  OK  ]
Enabling remote OVSDB managers                             [  OK  ]
Starting ovn-northd                                        [  OK  ]
Starting ovn-controller                                    [  OK  ]

b. The user has to be careful if setting paths to the ov[sn]-ctl
scripts. This is because we still install ovn-ctl from the ovs subtree
in the usr/share/openvswitch/scripts directory. E.g.:

$ export PATH=/home/dceara/local-builds/usr/share/openvswitch/scripts/:/home/dceara/local-builds/usr/share/ovn/scripts/:/home/dceara/local-builds/usr/bin/:$PATH
$ ovs-ctl start --system-id=local && ovn-ctl start_nb_ovsdb && ovn-ctl
start_sb_ovsdb && ovn-ctl start_northd && ovn-ctl start_controller
Starting ovsdb-server                                      [  OK  ]
Configuring Open vSwitch system IDs                        [  OK  ]
Starting ovs-vswitchd                                      [  OK  ]
Enabling remote OVSDB managers                             [  OK  ]
ovn-nbctl: unix:/home/dceara/local-builds/var/run/ovn/ovnnb_db.sock:
database connection failed (Connection refused)

<<< Stuck here because we're actually using ovn-ctl from
usr/share/openvswitch/scripts

I guess this will be fixed once the OVN code is removed from the OVS
repo. Until then, specifying the paths in the correct order (OVN
first, then OVS) works fine:

$ export PATH=/home/dceara/local-builds/usr/share/ovn/scripts/:/home/dceara/local-builds/usr/share/openvswitch/scripts/:/home/dceara/local-builds/usr/bin/:$PATH
$ ovs-ctl start --system-id=local && ovn-ctl start_nb_ovsdb && ovn-ctl
start_sb_ovsdb && ovn-ctl start_northd && ovn-ctl start_controller
Starting ovsdb-server                                      [  OK  ]
Configuring Open vSwitch system IDs                        [  OK  ]
Starting ovs-vswitchd                                      [  OK  ]
Enabling remote OVSDB managers                             [  OK  ]
Starting ovn-northd                                        [  OK  ]
Starting ovn-controller                                    [  OK  ]

So, with the small issues above that might need to be documented, the
patch works fine for me:

Thanks Dumitru for testing this patch.

Since usr/share/openvswitch/scripts/ or usr/share/ovn/scripts/ is not a

Right. Once OVN is removed from OVS, I think this should be fixed.
