How can I create /dev/null in a new mounted device?
« on: August 03, 2012, 03:00:13 PM »
I'm trying to create some minimal devices on a new mount point I created, but TCL doesn't come with makedev and there is no available package.

Code: [Select]
mkdir /mnt/ec2-fs/dev
/sbin/MAKEDEV -d <image_mountpoint>/dev -x console
/sbin/MAKEDEV -d <image_mountpoint>/dev -x null
/sbin/MAKEDEV -d <image_mountpoint>/dev -x zero

How can I do this on TCL?

Why are you trying to do this?
Filesystems  don't need device nodes on them.

I'm trying to create a TCL AMI following the guide below, but the instructions are targeted to Fedora distros. How would I modify the instructions in sections "Prepare for the Installation", "Install the operating system", and "Configure the Operating System" so that it works with TCL?
http://docs.amazonwebservices.com/AWSEC2/latest/UserGuide/creating-loopback-s3-linux.html

Does TCL have any equivalents to debootstrap?

Go to the main site: http://distro.ibiblio.org/tinycorelinux/welcome.html

Follow all the links at the top of the page, and read.

Core is not an Linux distribution.  It is a tool kit for building systems that
are fundamentally different than your normal Linux distribution.

If TCL is not a Linux distro then why is it listed here, here, and here?

Saw this in the intro:
In short, the Tiny Core distribution is like a customized version of the Linux kernel and other tools.

If it's not a distribution(operating system), then it's a kernel?

Anyways, thanks for your insightful help to my problem.

makedev is just a wrapper for mknod.

mknod /path/to/dev/null c 1 3
The only barriers that can stop you are the ones you create yourself.

Looking at your links to "Live media" and "List of Linux distributions that run from RAM" - those are exactly the types of systems the install guide you link to has very minimal compatibility as it assumes a scatter mode system running from read-write persistent storage...
