新型 LS-GL にハックキット 2.1（８）ftp サーバ、dhcp サーバ

新型 LS-GL に LS-GL/HS-DHGL ハックキット 2.0 をインストールしたら、電源ボタンで電源が落ちなかった。
原因は LS-GL が新型であることではなく、標準ファームの変更にインストーラが追従できていなかったため。

標準ファームへの依存を減らし、追従の必要を減らす形でハックキットを作り直したので、インストールしてテストする。

Please note that if you are installing the DHCP server for the first
time you need to configure it first. Please stop (/etc/init.d/dhcp
stop) the DHCP server daemon, edit /etc/dhcpd.conf to suit your needs
and particular configuration, and restart the DHCP server daemon
(/etc/init.d/dhcp start).

You also need to edit /etc/default/dhcp to specify the interfaces dhcpd
should listen to. By default it listens to eth0.

NOTE: dhcpd's messages are being sent to syslog. Look there for
diagnostics messages.

Starting DHCP server: dhcpd failed to start - check syslog for diagnostics.
