What does Ubuntu Core consist of?

Exactly what does Ubuntu Core consist of?

I know of a similar project called Ubuntu Mini Remix, which, while not an official Ubuntu project, is known to contain:

  • ubuntu-minimal metapackage
  • ubuntu-standard
  • casper
  • lupin-casper

What does Ubuntu Core contain?

What are the differences between the purposes of these two projects?

I would like to make sure of this before I choose a starting point to build my own Ubuntu derivative.


Solution 1:

Check the release directory for the ".manifest" files which list every package (eg. ubuntu-core-12.04.4-core-amd64.manifest). Ubuntu Core is just a minimal install of Ubuntu, you could make something very similar yourself by running:

mkdir chroot
debootstrap --arch=amd64 trusty chroot http://archive.ubuntu.com/ubuntu/

Ubuntu Core is just a minimal rootfs of around 60MB size whereas Ubuntu Mini Remix is a 200MB iso live image.
