From: Robert Yang Subject: [PATCH V4 08/11] mke2fs.c: add an option: -d root-directory Date: Sat, 1 Mar 2014 03:06:12 -0500 Message-ID: <1393661175-459-9-git-send-email-liezhi.yang@windriver.com> References: <1393661175-459-1-git-send-email-liezhi.yang@windriver.com> Mime-Version: 1.0 Content-Type: text/plain Cc: To: , Return-path: Received: from mail1.windriver.com ([147.11.146.13]:38846 "EHLO mail1.windriver.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1752090AbaCAIGf (ORCPT ); Sat, 1 Mar 2014 03:06:35 -0500 In-Reply-To: <1393661175-459-1-git-send-email-liezhi.yang@windriver.com> Sender: linux-ext4-owner@vger.kernel.org List-ID: This option is used for adding the files from a given directory (the root-directory) to the filesystem, it is similiar to genext2fs, but genext2fs doesn't fully support ext4.
