It is available for the i386, amd64, and armel architectures.
Ubuntu Core delivers a functional user-space environment, with full support for installation of additional software from the Ubuntu repositories, through the use of the apt-get command.
Be aware that Ubuntu Core is not a super small run-in-memory embedded distribution; it is the smallest implementation of Ubuntu that enables one to install other packages.
Some readers may find it useful to learn that the rootfs size of this distribution is more than 20MB.
One may use apt-get to install any set of packages. However, Ubuntu Core is designed for a device that requires a full operating system; Ubuntu Core can be configured and customized to fit the requirements of his or her device.
