* nix-unpack-closure: extract the top-level paths from the closure and
print them on stdout. This allows them to be installed, e.g.,
"nix-env -i $(nix-unpack-closure)". (NIX-64)
* `nix-install-package --help' (NIX-9).
* `nix-install-package --non-interactive': don't prompt or pause.
* Tests for nix-install-package.
* Security fixes: filter the values obtained from the nixpkg.
useful way to transfer the closure of a store path to another
machine.
These commands provide functionality previously possible through
`nix-push --copy'. However, they are much more convenient in many
situations (though possibly less efficient).
Example:
$ nix-pack-closure /nix/store/hj232g1r...-subversion-1.3.0 > svn.closure
(on another machine:)
$ nix-unpack-closure < svn.closure
Note that Subversion is added to the store, but not installed into a
user environment. One should do `nix-env -i
/nix/store/hj232g1r...-subversion-1.3.0' for that.
Another example: copy the application Azureus to the machine
`scratchy' through ssh:
$ nix-pack-closure $(which azureus) | ssh scratchy nix-unpack-closure
