- darwin installer: delete hardware report, not necessary - moves os-specific code from the darwin installer to to `poly_*` functions - adds profile.d support to the profile targets, which automatically handles many distros which don't have a /etc/bashrc but do have an /etc/profile.d - /bin/bash -> /usr/bin/env bash - document why each excluded shellcheck check is excluded - rename the multi-user to Daemon-based
