1. Start logging as early as possible. Currently several external commands are run before the logger is started. Therefore if a problem occurs with those commands, it is not covered by the log.
2. Reduce DNS queries. Pcsd asks the name resolver for the local node name / IP four times. If requested info is not present in /etc/hosts, DNS servers are contacted. This is visible in pcsd strace. Two of the requests come from imported ruby libraries / gems. Other come from pcsd code. We want to focus those two from our code and modify code so the queries are run only if necessary.
