editor's review




Welcome to the Precise Pangolin edition of Ubuntu Core, an open source software project that provides you with a minimal rootfs (root filesystem) for creating feature-rich Ubuntu-based operating systems with minimum effort.

Supported architectures and availability

Ubuntu Core 12.10 was officially announced by Canonical on October 18, 2012 along with several other Ubuntu flavors, and supported until May 16, 2014. It is available for download as tar archives for the 32-bit (i386), 64-bit (amd64), ARMhf (ARM Hard Float) and PPC (PowerPC).

Getting started with Ubuntu Core

First of all, the user must download the appropriate Ubuntu Core tar archive for his or her target architecture before starting the building process (see above for supported hardware platforms). Second of all, you have to download the boot loader and Linux kernel archives for the target device.

The user must first prepare the target drive by creating at least one partition and format it with a supported and stable Linux file systems, such as EXT2, EXT3 or EXT4. Then, he or she must extract the content of the Ubuntu Core archive on the respective partition.

Next, extract and install the Linux kernel and boot loader packages that you've downloaded on the first step, set up users and passwords (at least one) and add them to the adm and sudo groups. If your installation needs certain kernel modules, don't forget to add them in the /lib/modules/$(uname -r) directory.

To verify if your system works, boot the target disk. Then, you will be able to install extra packages with the well known apt-get command used in all Debian-based operating systems, including Ubuntu.

Bottom line

All in all, Ubuntu Core 12.10 is a unique project that allows anyone with basic Linux knowledge to build and deploy Ubuntu-based operating systems on desktop and server machines, as well as on embedded devices in a shortest time as possible and with minimum effort. This version is no longer supported and has been archived for historical purposes only.
