what pre-creates log files?

What creates log files during installation time?

I tried searching through base sets, sysinst source, mtree specs, but 
haven't found yet.

For example, my system complains about missing /var/log/xferlog which is 
in syslogd.conf but not on my system. I am trying to track down source to 
see if this is a problem with installation or not.
