[syslog-ng] syslog-ng and systemd

Hello users,

Fedora 15 (and later) uses systemd as init-replacement.
Currently, I'm building a fedora package for syslog-ng version 3.2.x.

It is based on a git-snapshot dated April 24th. Is there a way to signal
syslog-ng to reload it's configuration other than HUPing its pid?

The documentation of systemd[1] says:

ExecReload= should be specified for all services supporting reload. It
is highly recommended to add code here that synchronously reloads the
configuration file here (i.e. /bin/kill -HUP $MAINPID is usually a poor
choice, due to its asynchronous nature). Omit this option if your
service does not support reloading.

I would highly appreciate not to maintain a pidfile. Newer linux kernels
support so called cgroups. Those can be used to group processes. Systemd
creates a cgroup for each service and starts in our case syslog-ng in
this cgroup. When no process runs in syslog-ng cgroup, the process
exited and must be restarted. systemd takes care of this.

Again, is there any other way to signal syslog-ng to reload its config?

Thanks,

Matthias
