We also exit earlier, we don't display that we are even trying to start.
When we detect the agent is already running we exit right away with a message.
With LSB there is no need for having different init script for different distributions.
This init script should be fully LSB compliant and should work on all Linux platforms we support.
RHEL, (Open)SUSE, Debian and Ubuntu all support at least LSB 3.1
The init script was waiting for cloudbr0 to come up, but it's not mandatory that this bridge is available.
We now wait for at least one bridge to be up before starting the cloud agent.
Notice, even after this fix, there would be 2 entries in the mshost table, after
mgmt server restarted. But it should be harmless, since only one of them is
"Up".
Some message in the log would indicate something wrong with the original mshost
entry, but still, it seems harmless.
