Subject: [PATCH] config: set chain directory _after_ the command line+config
 has been parsed
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This commit fixes a bug introduced by the new multi-chain features of
and which disallowed multiple nodes from beings started locally.
Previously if two local nodes were set to, the _same_ chain, then
they’d both share the same chain data directory which would prevent one
of the nodes from being able to start up properly.
