editor's review




Welcome to the Saucy Salamander edition of Ubuntu Core, a unique project that has been designed from the ground up to provide users with a minimal root filesystem (rootfs) of Ubuntu 13.10 for building custom Ubuntu-based operating systems.

Supported architectures, availability

Ubuntu Core 13.10 was officially announced by Canonical on October 17, 2013 and it will be maintained until July 2014. As usual, users can download it as tar archives for the 32-bit (i386), 64-bit (amd64), PPC (PowerPC) and ARM Hard Float (ARMhf) instruction set architectures.

How to build your own Ubuntu OS

Those of you who create custom Ubuntu-based operating systems using previous versions of this project, need no instructions, but new users should know that they will have to first download the Ubuntu Core tar archive for the target architecture, as well as a Linux kernel and boot loader.

Then, you must create at least one Linux partition on the target drive and format it with a stable and supported Linux filesystem, such as EXT4, EXT3 or EXT2. Extract the contents of the Ubuntu Core archive on the newly create partition, compile and install the Linux kernel and install the boot loader. Don't forget to add extra kernel modules in the /lib/modules/$(uname -r) directory.

To verify if your custom Ubuntu OS works properly, boot the target device. It everything works well, you should be able to add additional packages with the apt-get command. You can install as many packages as you want, add a desktop environment and X11 display server, as well as third-party drivers and packages.

Bottom line

With the Ubuntu Core 13.10 release, this special Ubuntu project proves once again that it is quite popular among advanced Linux users with special requirements who are looking for an easy-to-use method for building custom operating systems based on Ubuntu.
