sysklogd in RH4.2 always opens a UDP listen socket, even when -r
is not specified on the command line. It doesn''t check the file
descriptor
when -r is off though, but the behaviour still irritates the
system administrator greatly (see also the recent bugtraq messages
about this).
Here is a patch to fix this:
