I've more or less relegated myself to mailing-list-only membership.
There've been some great meeting topics of late, but my schedule and
PLUG conflict in deep and murky ways. :-/

CentOS 6 will give you a good view of current enterprise Linux. Fedora
16 -- or if you're really brave, the alpha release of Fedora 17 --
will point you toward the future.
Fedora 16, in particular, has forced me to add systemd stuff to my
shellcommand rules. If I push out, say, an updated version of
/etc/smartd.conf to my hosts, I now need rules for Debian systems, Red
Hat (and derivatives) using SysV, and Red Hat (and derivatives) using
systemd:
smartd_reload.debian::
"/etc/init.d/smartmontools reload"
smartd_reload.redhat.!systemd_s::
"/etc/init.d/smartd reload"
smartd_reload.redhat.systemd_s::
"/bin/systemctl try-restart smartd.service"
If you've got hardware capable of it, another good avenue to
investigate is KVM and native Linux virtualization. I use CentOS 6
with KVM to host several Debian, CentOS, Fedora, and even Windows
virtual machines.
