To be clear (because I was wondering why all these commands were required), installing a version of Ubuntu on your phone just requires Complete Linux Installer http://the.taoofmac.com/space/blog/2013/03/30/2107 (and busybox and loopback filesystem etc.)
This post is specifically about creating a new image from scratch to use with the Complete Linux Installer rather than using the ones that are provided for download in the app.
Also, this has been possible since basically the first version of Android: http://www.saurik.com/id/10 . It's just a chroot jail, taking advantage of the fact that there are ARM versons of Debian/Ubuntu. Complete Linux Installer and other similar apps are nice because they save you the trouble of remembering a bunch of commands or downloading and running a script, but even they are doing nothing besides downloading an image and running a script.
This is far from a usable experience. Notably, Android doesn't have an X server so you have to use VNC to get a GUI so a GUI is effectively useless. It's kind of handy to have proper GNU userland instead of Busybox sometimes and you can do silly things like run a local webserver and edit files using Emacs/vim/etc, but unless you're on a tablet with a keyboard attached somehow it's not practical at all. This has no relation to Ubuntu's efforts to make a proper port of Ubuntu to phones.

Has anyone done this? What're your thoughts on the OS?
