For some unclear reason, we get occasional reports from people who do
not have /usr/sbin on their PATH that the installer fails. It's a
standard part of the PATH, so I have no clue what they're doing to
remove it--but it's also fairly cheap to avoid.
Some of the changes in #3788 to support non-systemd Nix installs
don't appear to be aware that the darwin installer exists, which
resulted in some skipped steps and inappropriate instructions.
On Catalina, the /nix filesystem might not be mounted at start time.
To avoid this service not starting, we need to keep the launch agent
outside of the Nix store. A wait4pid will hold for our /nix dir to be
mounted.
Fixes#3125.
- 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
The installer will error out if a user's shell configuration includes any mention of ~nix-profile~, even if this is in a comment. This change is designed to do the bare minimum to ignore lines beginning with a `#`.
In particular, drop the "build-" and "gc-" prefixes which are
pointless. So now you can say
nix build --no-sandbox
instead of
nix build --no-build-use-sandbox
