ReadConfig and GetConfig differed in one thing — what happens when the file is
absent — and neither name said which was which:
- ReadConfig -> ReadOrGenerateConfig (reads it, or generates one in memory)
- GetConfig -> GetExistingConfig (reads it, or fails)
Three comments went with them:
- GetConfig's said "return with Config and if it was created. Errors out if it
does not exist", which described a bool it does not return and a creation it
never performs.
- ReadConfig's explained that it does not write, which is what a reader is
supposed to do anyway.
- Server.getConfig's said it "errors out if it does not exist", which it does
not — it resolves a default config, and now provisions the identity too.
