confusing "I need to load the permanent master identity key" line
I ran my Tor as a bridge for the first time in apparently a while, and it gave me this message on startup:
Nov 13 02:26:37.814 [notice] It looks like I need to generate and sign a new medium-term signing key, because the one I have is expired. To do that, I need to load the permanent master identity key.
I've never done anything about permanent master identity keys or anything on this Tor. I assume that this log line means that Tor did everything for me? The "I need to load" part is confusing because it makes me think that there's something more to be done -- there were no follow-up log lines about how it worked or succeeded or is happy or anything now.
Looks related to commit c88a8a7c, which went into Tor 0.2.7.3-rc and might have come from #16685 (moved).
