+====== 開発環境用コンテナのセットアップ(Ubuntu以外のディストリビューション使用の場合) ======
+Ubuntu 以外のディストリビューションを利用している場合でも、クロスコンパイラなどの導入を考えると\\
+Ubuntu の環境を構築するのがお勧めです。
+仮想マシンを作成するとリソースを消費しますので、コンテナ(LXC((https://ja.wikipedia.org/wiki/LXC)) (([[http://knowledge.sakura.ad.jp/tech/2108/|15分で分かるLXC(Linux Containers)の仕組みと基本的な使い方 - さくらのナレッジ]])))でUbuntuの環境を作成する方法を紹介します。
+ホストの環境は Debian(Jessie) を想定しています。
+※ [[.emdebian_toolchain:start]] (([[http://qiita.com/myahal@github/items/fc332e53713df244518f|armhfクロスコンパイル環境を作る - Qiita]]))もあるようです。

+===== Ubuntu コンテナの作成 =====
+==== LXC パッケージの導入 ====
+LXC を使用するためのパッケージを導入します。

+==== 設定 ====
+Debian の lxc-create では細かい設定をしてくれないので、手動で設定を変更します。
+=== /var/lib/lxc/trusty/config の編集 ===
+<code>
+root@jessie:~# nano -w /var/lib/lxc/trusty/config
+</code>
+<code>
+# Template used to create this container: /usr/share/lxc/templates/lxc-ubuntu
+# Parameters passed to the template: -r trusty

+# Network configuration
+lxc.network.type = veth
+lxc.network.link = lxcbr0
+lxc.network.flags = up
+lxc.devttydir = lxc
+</code>
+\\
+=== lxcbr0 I/F の作成 ===
+bridge-utils パッケージを導入します。
+<code>
+root@jessie:~# apt-get install bridge-utils
+</code>
+/etc/network/interfaces を編集し、lxcbr0 の設定を追加します。
+<code>
+root@jessie:~# nano -w /etc/network/interfaces
+</code>
+<code>
+# This file describes the network interfaces available on your system
+# and how to activate them. For more information, see interfaces(5).

+\\
+=== dnsmasq の導入 ===
+DHCPサーバ/DNSキャッシュ用 dnsmasq パッケージを導入します。
+<code>
+root@jessie:~# apt-get install dnsmasq
+</code>
+/etc/dnsmasq.conf を編集します。
+<code>
+root@jessie:~# nano -w /etc/dnsmasq.conf
+</code>
+下記エントリを追加します。
+<code>
+interface=lxcbr0
+bind-interfaces
+dhcp-range=192.168.8.50,192.168.8.150,12h
+</code>
+\\
+=== iptables の設定 ===
+iptables の設定を自動化するため、iptables-persistent パッケージを導入します。\\
+導入時に現在のルールを保存するか聞かれるため、eth0 への MASQUERADE 設定(コンテナから外へ抜けるため) を追加しておきます。
+<code>
+root@jessie:~# iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
