Thanks, this is in git now: https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=5054a5e3d651e02f31e4571bac1dd0ad7fd64b7a When trying to initialize vault, I experienced this problem: $ vault init Error initializing Vault: Put https://127.0.0.1:8200/v1/sys/init: http: server gave HTTP response to HTTPS client The problem is solved by using -address http://127.0.0.1:8200 or using VAULT_ADDR=http://127.0.0.1:8200 environment variable.
