Initial Systemd article

[Ryan Lerch]

In the meeting last week, i was tasked with editing the first systemd 
article here:

http://fedoramagazine.org/?p=10001

however, on review, i found that this was quite far from what we 
discussed in the meeting for the first entry-level article in the 
series. So i created a new article for Part 0 (as i am calling it) of 
the systemd series:

http://fedoramagazine.org/?p=10202

It basically covers the question of what an init system is, and what it 
does -- with little about systemd itself (hence the part 0).

Any thoughts on if this is a good start to the series, (and also a 
technical review would also be good).

cheers,
