Hey Vladimir,
Thanks for filling in the gaps. This installation that I'm on is a fresh Fedora 20 (Heisenbug) installation from media.
Here is my `yum history info 1` (with some editing for brevity):
sudo yum history info 1
Loaded plugins: langpacks, refresh-packagekit
Transaction ID : 1
Begin time : Wed Jan 15 19:04:28 2014

End rpmdb : 1559:ddc0bb756493d614f12d21ac3bed86c1d42a80d4
User : System <unset>
Return-Code : Success
Packages Altered:
<snip>
Install rsyslog-7.4.2-2.fc20.x86_64 @anaconda
</snip>
....and if I rpm -qa | grep -i syslog - that's the only package that I see come up. I'd venture to guess the fact that I added on nearly every optional group during the install may have included that package. Even so in any large-scale deployment scenario I too prefer a centralized log server for easier review/management/shipment (to splunk or whatever your preferred log parser may be).
Thanks again for filling in my gaps though!
