[arch-general] systemd

[solsTiCe d'Hiver]

hi.
since the recent news, I have decided to give a try to systemd.

I am following the wiki page about it
https://wiki.archlinux.org/index.php/Systemd

Sorry for the newbie question but,
why
are /etc/hostname, /etc/vconsole.conf, /etc/timezone, /etc/locale.conf
not in the systemd package ?
I know they are very specific to my system but so is rc.conf but it is
nonetheless part of initscripts

Also, I vaguely remember that service are symlinked
in /etc/systemd/.../something from /usr/lib/systemd/something.
This step is not even mentionned in the wiki page

In fact, I am looking at a tutorial to configure my system with systemd
and all the service/daemon I already use.
I don't even talk about lvm/cryptsetup stuff...

So, how do you guys have done this ? I don't mind if you tell me to RTFM
but where is the manual ?

I need to read some doc. to understand how this thing works too.
