以前、ReadyNAS 316 に 7-Zip 導入できなかった という記事を書いたのだけれど、拍子抜けするぐらいあっけなく導入できた。
難しく考えすぎると良くない...
7-Zip の公式サイトを見ると、コマンドライン用の 7-Zip for Linux: console version も上がっています。
これを SSH で NAS に配置してあげれば OK。

ReadyNAS 316 は CPU に Atom D2701 を使用していて OS も 64bit 版なので、7-Zip も 64bit 版の 7z2501-linux-x64.tar.xz をダウンロードします。

ダウンロードした 7-Zip を解答して readme.txt を見ると、コマンドライン用の 7z が 2つ用意されていることを確認できます。
※7zzs がフルセット。
$ cat readme.txt | head -n 30 | tail
This distribution package contains the following files:
7zz - standalone console version of 7-Zip (version compiled for dynamic system library linking)
7zzs - standalone console version of 7-Zip (version compiled with static system library linking)
readme.txt - this file
License.txt - license information
History.txt - History of 7-Zip
MANUAL - User's Manual in HTML formatバージョン、オプションはこんな感じ。
