%description
Nix is a purely functional package manager.
It allows multiple versions of a package to be installed side-by-side,
ensures that dependency specifications are complete,
supports atomic upgrades and rollbacks,
allows non-root users to install software, and has many other features.
It is the basis of the NixOS Linux distribution,
but it can be used equally well under other Unix systems.

See the README.fedora.md file for setup instructions.


%package        core
Summary:        Core nix tool
%ifarch x86_64 aarch64 ppc64le
#Recommends:     busybox
%endif

%description    core
This package provides the core nix tool for modern flake-based commands.

Most users should probably install nix-legacy as well,
or the main nix package for a complete default setup.

See the README.fedora.md file for setup instructions.


%package daemon
Summary:        The nix daemon for multiuser mode
BuildArch:      noarch
Requires:       nix-core = %{version}-%{release}
Requires:       nix-system = %{version}-%{release}
Requires:       systemd

%description daemon
This package provides nix-daemon and associated files.


%package devel
Summary:        Development files for nix
Requires:       nix%{?_isa} = %{version}-%{release}

%description devel
This package contains library and header files for
developing applications that use nix.

Note the API is considered unstable and upstream does not recommend its usage.


%package        filesystem
Summary:        Filesystem for nix
BuildArch:      noarch

%description    filesystem
The package provides the /nix root directory for the nix package manager.


%package        legacy
Summary:        Nix classical commands
BuildArch:      noarch
Requires:       nix-core = %{version}-%{release}

%description    legacy
This package provides the symlinks for the older nix-* commands.


%if %{with tests}
%package test
Summary:        Nix test programs
Requires:       nix%{?_isa} = %{version}-%{release}

%description test
This package provides the nix-test programs.
%endif


%package        system
Summary:        Nix directories and sysusers setup
BuildArch:      noarch
Requires:       nix-filesystem = %{version}-%{release}

%description    system
This package sets up the nix directories and sysusers.
