Possible risk with these 2 lines.
docker kill swss will trigger swss service stop(), and will docker stop syncd. Then it will trigger syncd service stop().
But you manually systemctl stop syncd again. #Closed

I tested with following code:
#!/bin/bash
docker kill swss
echo $?sudo systemctl stop syncd
echo $?
sonic prompt # ./test.sh
swss
0
0
Stopping a service after it has been stopped is no-op with success result. Does this address your concern? or are you thinking about something else?

Kill swss docker will cause service swss to fail, systemctrl will then stop swss as result. If the flag is not set, swss will also stop syncd without letting syncd to warm shutdown. Signed-off-by: Ying Xie <[email protected]>

- What I did
This PR is enabled by sonic-buildimage PR 2238
In test, we found that when issue-ing "docker kill swss", it causes swss service to become FAILED. As result, systemctrl will execute swss stop script. Which will also stop syncd service if the warmboot flag is not set in warm boot case. Before sonic-buildimage PR 2238, this will cause syncd process being killed instead of shutting down properly in both warm/fast reboot cases. Most importantly switch_remove() is not called. For both warm boot and fast reboot, properly shutting down syncd process is very crucial to the operations.
