Changes: - `jaq` should probably live in `/usr/local/bin` with other third-party sourced binaries. - `swaks` install properly with just `tar`, no `mv` + `rm` needed. - Added Smallstep `step` CLI. This serves similar purpose to `openssl` commands, but is generally nicer for usage with generation and inspection of certs/keys. I've talked up using in DMS a few times in the past for our TLS helper and unifying DKIM support (_instead of separate OpenDKIM/Rspamd generators_). - Including `step` for both AMD64 / ARM64 archs needs the alternate naming convention that it's published to GH releases with. - Added commentary about the `tar` usage. The ownership is a common concern with GH release sources, technically a non-issue when running as `root` |
