From 22c1fdfbd320379a09f4a670126bc28cdc383b87 Mon Sep 17 00:00:00 2001 From: Philip Withnall Date: Thu, 21 Sep 2017 16:00:05 +0100 Subject: [PATCH] lib/repo: Change resolve_keyring_for_collection() to return a remote Instead of returning just the keyring filename, return the entire OstreeRemote, which has the keyring filename as one of its members. This will simplify some upcoming changes, and allows slightly improved debug logging.
