The systemd wiki entry:

I found to be very painless when I switched over using it.
]]>Starting from the beginning, I did a full system upgrade last week with pacman -Syu, and there were a ton of things that needed upgrading. Probably about 40 packages if I remember. I didn't think there would be that many. Anyway, the first problem I noticed after upgrading was that the Suspend option in XFCE was disabled. It's still there, but clicking on it does nothing, and it's discolored as well.
At this point, I decided a restart was in order. During the boot process, when it came time to start up dbus - which is the second thing on my daemons list - it said FAILED in big red letters where it usually says DONE. However, after the boot finishes and I log in, putting `rc.d list` into a terminal shows dbus as running and automatically started.
I read a little about dbus on your wiki, which is excellent by the way, and it says that dbus is responsible for sending system messages. I don't see how these two issues can be related, but like I said, I'm not an expert.
Here are some system specs that may or may not be related/helpful:
