reflum, About the warning: 'Warning: Restore failed' is normal as it can not restore old state on first startup as there is no old state to restore. This is normal to happen on install. Maybe we can do something about the warning but for the moment it can just be ignored.
About the chown in init script: Yes. This is a bug. It is on TODO list of upstream and will likely be fixed by next release. About the fail to start: It seems it fails to start from what you said. Is there any roaraudio-server running? I recommend the use of roard from roaraudio package. You can confirm with something like: ps aux | grep roard -- Philipp. (Rah of PH2)
