After running logrotate, Puppet starts writing it's logs into /var/log/puppet/masterhttp.log-20130616. How come it doesn't keep logging in /var/log/puppet/masterhttp.log?

It seems normal behavior is renaming the original log-file and start with a clean fresh log-file to start writing in that log file, keeping the other file as a log-archive.

[root@puppetmaster puppet]# ls -al
total 97520
drwxr-x---.  2 puppet puppet     4096 Jun 16 03:24 .
drwxr-xr-x. 12 root   root       4096 Jul  1 09:11 ..
-rw-r--r--.  1 puppet puppet        0 Jun 16 03:24 masterhttp.log
-rw-rw----.  1 puppet puppet 99847187 Jul  1 09:19 masterhttp.log-20130616
[root@puppetmaster init.d]# cat /etc/logrotate.d/puppet
/var/log/puppet/*log {
  missingok
  notifempty
  create 0644 puppet puppet
  sharedscripts
  postrotate
    pkill -USR2 -u puppet -f /usr/sbin/puppetmasterd || true
    [ -e /etc/init.d/puppet ] && /etc/init.d/puppet reload > /dev/null 2>&1 || true
  endscript
}
[root@puppetmaster init.d]#

How can I make Puppet log to /var/log/puppet/masterhttp.log and not to /var/log/puppet/masterhttp.log-20130616?

Even restarting puppet doesn't make it log into /var/log/puppet/masterhttp.log instead of /var/log/puppet/masterhttp.log-20130616.
