@yxieca Please review this.

If this is the right argument string on BF platform. By all means go ahead.

I am curious why you put sai.profile under /tmp/?

Can you follow other platform's sample to mount device folder to syncd. If the sai.profile is generated by a template, please follow https://github.com/Azure/sonic-buildimage/blob/master/platform/broadcom/docker-syncd-brcm/start.sh#L45 to put it to a consistent place.

If you need to adjust sai.profile location, please start anther PR. This comment doesn't mean to ask you to change it in this PR.

I will submit a PR to fix the name of syncd process in the monit config file.

I suggest we close this PR in favor of #4033, in which we do not check for any parameters. This solution will be more future-proof, in that if any parameters change, we will not need to make any updates here.
