Description of problem: dovecot starts before network initialization is complete Version-Release number of selected component (if applicable): dovecot-2.2.13-1.fc20.x86_64 How reproducible: Configure dovecot to listen on explicit static interface address. Steps to Reproduce: 1. reboot system Actual results: dovecot generates an error indicating its interface does not exist. Expected results: dovecot starts Additional info: This is a generic problem with all services binding to explicit interface addresses and depending on network.target only. network.target does not make sure that all statically configured interfaces are up. Onle network-online.target does that. Therefore the solution for all configurable services not supporting IP_FREEBIND is to change the dependency from network.target to a depedency on network-online.target: Requires=network-online.target After=network-online.target Other network services are affected as well so this bug report is only one in a row.
