More information from the developers:
In contrast with the Live CD, this disk allows permanent installation of Linux and genealogical software on your computer’s hard drive. This way you achieve adequate speed and the ability to save your data, and can do real work with your Linux software. In particular, it makes a perfect gift for genealogists who want to work on Linux.
This disc contains a complete Ubuntu installer and, in addition to the regular Breezy, features pre-installed GRAMPS, GeneWeb, and LifeLines applications, as well as GraphViz program to draw pretty graphs in GRAMPS. Everything is similar to the Live CD, except that this is a permanent setup.
To download the CD image, please refer to the bottom of this page (gramps-project.org) for both ftp/http and Bittorent downloads. The Linux Genealogy Live CD was reviewed a few weeks ago at Eastman’s Online Genealogy Newsletter.
