uboot: (firmwareOdroidC2/C4) don't invoke patch tool, use patches = [] instead
https://github.com/NixOS/nixpkgs/blob/master/pkgs/stdenv/generic/setup.sh#L948 this can do it nicely. Signed-off-by: Anton Arapov <anton@deadbeef.mx>

<title>Declarative Container Specification</title>
|
||||
<para>
|
||||
You can also specify containers and their configuration in the
|
||||
host’s <literal>configuration.nix</literal>. For example, the
|
||||
following specifies that there shall be a container named
|
||||
<literal>database</literal> running PostgreSQL:
|
||||
</para>
|
||||
<programlisting language="bash">
|
||||
containers.database =
|
||||
{ config =
|
||||
{ config, pkgs, ... }:
|
||||
{ services.postgresql.enable = true;
|
||||
services.postgresql.package = pkgs.postgresql_10;
|
||||
};
|
||||
};
|
||||
</programlisting>
|
||||
<para>
|
||||
If you run <literal>nixos-rebuild switch</literal>, the container
|
||||
will be built. If the container was already running, it will be
|
||||
updated in place, without rebooting. The container can be configured
|
||||
to start automatically by setting
|
||||
<literal>containers.database.autoStart = true</literal> in its
|
||||
configuration.
|
||||
</para>
|
||||
<para>
|
||||
By default, declarative containers share the network namespace of
|
||||
the host, meaning that they can listen on (privileged) ports.
|
||||
However, they cannot change the network configuration. You can give
|
||||
a container its own network as follows:
|
||||
</para>
|
||||
<programlisting language="bash">
|
||||
containers.database = {
|
||||
privateNetwork = true;
|
||||
hostAddress = "192.168.100.10";
|
||||
localAddress = "192.168.100.11";
|
||||
};
|
||||
</programlisting>
|
||||
<para>
|
||||
This gives the container a private virtual Ethernet interface with
|
||||
IP address <literal>192.168.100.11</literal>, which is hooked up to
|
||||
a virtual Ethernet interface on the host with IP address
|
||||
<literal>192.168.100.10</literal>. (See the next section for details
|
||||
on container networking.)
|
||||
</para>
|
||||
<para>
|
||||
To disable the container, just remove it from
|
||||
<literal>configuration.nix</literal> and run
|
||||
<literal>nixos-rebuild switch</literal>. Note that this will not
|
||||
delete the root directory of the container in
|
||||
<literal>/var/lib/nixos-containers</literal>. Containers can be
|
||||
destroyed using the imperative method:
|
||||
<literal>nixos-container destroy foo</literal>.
|
||||
</para>
|
||||
<para>
|
||||
Declarative containers can be started and stopped using the
|
||||
corresponding systemd service, e.g.
|
||||
<literal>systemctl start container@database</literal>.
