Hi,  
I was trying to run kopia repository create using os/exec Start() command, and i see that stdout prints only the global policy and stderr prints the “Initializing repository …” message. Is this the correct behaviour I am seeing?

I am checking stderr to check if repo create is successful, is there any other way to check if this command is successful?

**stdout** : Retention:\n Annual snapshots: 3 (default)\n Monthl  
snapshots: 24 (default)\n Weekly snapshots: 4 (default)\n Daily snapshots: 7 (default)  
Hourly snapshots: 48 (default)\n Latest snapshots: 10 (default)\nCompression disabled.\n"

Exit code zero will indicate success as is typical in Unix.

Yup that is what I am using. Was curious to know output being printed to stderr. Any reason for this?

No real reason, this bit of a code requires some cleanup.
