From mboxrd@z Thu Jan 1 00:00:00 1970 From: Markos Chandras Date: Mon, 5 Nov 2012 09:44:54 +0000 Subject: [Buildroot] [PATCH v3] fs/common: Create initial console device Message-ID: <1352108694-11875-1-git-send-email-markos.chandras@gmail.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: buildroot@busybox.net From: Markos Chandras A /dev/console node must be present in rootfs when the Linux kernel boots otherwise the kernel will print the following warning: "Warning: unable to open an initial console" This is because when we use an initramfs the /dev directory is not populated at this point. This can cause problems when a program (e.g ldso with early debugging enabled) opens a standard file descriptor for read/write before these descriptors are actually created by the init process later on.
