GNU Guix 0.1 released!
Version 0.1 of the GNU Guix functional package manager and its baby distribution of user-land software has been released. See http://lists.gnu.org/archive/html/bug-guix/2013-01/msg00191.html for the original announcement.
In addition to standard package management features, Guix supports
transactional upgrades and roll-backs, unprivileged package management, per-user profiles, and garbage collection (more details in the manual.)
The distro is not a bootable distro yet, but rather one to be installed on top of a running GNU/Linux system. It includes GNU libc 2.17, GCC 4.7.2, GNU Emacs 24.2, GNU Guile 2.0.7, and more.
Building the distribution is a cooperative effort, and you are invited to join!
