I am unfamiliar with the concept that one can setup syslogd to ignore
HUP signals, but that doesn't mean that it isn't true.  The typical
LDM setup is for hupsyslogd (and rpc.ldmd) to have setuid root privilege
(will run as root).  An invocation of hupsyslogd then sends a HUP to
syslogd as root, and a HUP signal tells the LDM to reread its configuration
file, /etc/syslog.conf.

I will ask our system administrator if one can setup syslogd so that 
a HUP won't work to see if perhaps you are doing a lot more work than
you need to.
