From the Mageia 2 Alpha 3 release notes, "Following the standardisation effort going on in other distributions, Mageia has decided to adopt systemd for booting. This would lead to a simpler boot process, and easier maintenance. More details can be found on the systemd website. The option of keeping the current init system will be offered for people who prefer to wait a little and switch with a next release."
The switch to systemd comes after Mandriva, for which Mageia is derived, switched to systemd with their Mandriva Linux 2011 release. Fedora, openSUSE, and Gentoo are among the other Linux distributions to have adopted this System V init replacement.
Other features of Mageia 2 Alpha 3 include shipping the Linux 3.2 stable kernel (but it will be replaced by Linux 3.3+ for its final release), glibc 2.14.1, a near-final KDE 4.8 snapshot, GNOME 3.3.3 (also in the run-up to GNOME 3.4), Sugar 0.95 from the OLPC project, GCC 4.6.2, and various package updates.
Additional details on the Mageia 2 Alpha 3 release can be found from the Mageia blog.
The final release of Mageia 2 is set for early May while the first beta release is expected in just over one month.
