[syslog-ng]logrotate question (not working with syslog-ng)...

The standard compile options for syslog-ng put the pid file (which just
contains the process ID) into '/var/run/syslogd-ng.pid', but logrotate
and related things expect the pid to be in '/var/run/syslogd.pid', which
is syslogd's standard location.  Aside from the filename, syslogd and
syslog-ng act the same on receipt of a SIGHUP (by design), and most apps
just pick up the pid from that file.
