# all_wrap="/usr/bin/perf record --call-graph -"
# the normal daemon command is added to this at the end.

we already have supervised to start frr process, it is good to unified all process management inside the docker. We have unified way to manage process restart, docker restart, process crash messages. I do not really understand why we need to change that.

I don't really understand either why we had to change from systemd in the first place. There was no functional requirement in the first place to change to supervisord. I don't see the goodness in unifying all process management inside the docker under supervisord especially since we ended up with multiple problems out of it. The routing application should be standalone and free of any such dependancies. It also doesn't need this unification. These changes were agreed in the August meeting we had and I sent meeting minutes. I also fail to understand why we are holding this PR as hostage when it fixes 5 blocking critical issues for a month now.
