<refsection><title>Description</title>
|
||||
|
||||
<para><command>nix-copy-closure</command> gives you an easy and
|
||||
efficient way to exchange software between machines. Given one or
|
||||
more Nix store paths <replaceable>paths</replaceable> on the local
|
||||
machine, <command>nix-copy-closure</command> computes the closure of
|
||||
those paths (i.e. all their dependencies in the Nix store), and copies
|
||||
all paths in the closure to the remote machine via the
|
||||
<command>ssh</command> (Secure Shell) command. With the
|
||||
<option>--from</option>, the direction is reversed:
|
||||
the closure of <replaceable>paths</replaceable> on a remote machine is
|
||||
copied to the Nix store on the local machine.</para>
|
||||
|
||||
<para>This command is efficient because it only sends the store paths
|
||||
that are missing on the target machine.</para>
|
||||
|
||||
<para>Since <command>nix-copy-closure</command> calls
|
||||
<command>ssh</command>, you may be asked to type in the appropriate
|
||||
password or passphrase. In fact, you may be asked
|
||||
<emphasis>twice</emphasis> because <command>nix-copy-closure</command>
|
||||
currently connects twice to the remote machine, first to get the set
|
||||
of paths missing on the target machine, and second to send the dump of
|
||||
those paths. If this bothers you, use
|
||||
<command>ssh-agent</command>.</para>

the target machine does not have direct access to the Nix store

(i.e., if the target machine has a multi-user Nix installation),
|

then the target machine will check the dump against

<filename>/nix/etc/nix/signing-key.pub</filename> before unpacking
|

it in its Nix store. This allows secure sharing of store paths

between untrusted users on two machines, provided that there is a

trust relation between the Nix installations on both machines
