A:

There seems to be a problem with the distributed version of the TCP wrappers library. Edit the src/conf.h file and comment out the #define HAVE_LIBWRAP 1 line. This means that you will not be able to use TCP wrappers security however. You might prefer to collect and compile a new version of TCP wrappers.

Q:

Linux insists on rebuilding the message of the day file each time it boots, but that means I keep losing the messages I leave there.

A:

Add the following to your configuration files to comment out the offending lines in the startup scripts:

editfiles:

   linux::

    { /etc/rc.d/rc.S

    HashCommentLinesContaining "motd"
    }
