|

|
||
<para>The command <command>nix-pack-closure</command> packs the
|
||
contents of the store paths <replaceable>paths</replaceable> and
|
||
<emphasis>all their dependencies</emphasis> into a single file, which
|
||
is written to standard output. (That is, it
|
||
<emphasis>serialises</emphasis> <replaceable>paths</replaceable>.)
|
||
The output can then be unpacked into the Nix store of another machine
|
||
using <command>nix-unpack-closure</command>.</para>
|
||
|
||
<para>Together, <command>nix-pack-closure</command> and
|
||
<command>nix-unpack-closure</command> provide a quick and easy way to
|
||
deploy a package to a different machine. However, as the output of
|
||
<command>nix-pack-closure</command> tends to be rather large (since it
|
||
contains all dependencies), it’s not very efficient.
|
||
<command>nix-push</command> and <command>nix-pull</command> are more
|
||
efficient, but are also a bit more cumbersome to use.</para>
