[PATCH v6 11/15] init-db: die on config errors when initializing empty repo

From
Patrick Steinhardt <ps@pks.im>
Date
Feb 22, 2016, 11:23 UTC
Message-ID
<1456140216-24169-12-git-send-email-ps@pks.im>

When creating an empty repository with `git init-db` we do not check for error codes returned by `git_config_set` functions. This may cause the user to end up with an inconsistent repository without any indication for the user.

Fix this problem by dying early with an error message when we are unable to write the configuration files to disk.
