Btw, /etc/inetd.conf doesn't actually come from xinetd and the string
/etc/inetd.conf doesn't actually occur in xinetd.lst.gz so this is a
very good example of why it is dangerous to roll your own tools if you
don't know what is going on.  From the above, a novice user would assume
that xinetd contained /etc/inetd.conf.

/etc/inetd.conf is a generated file so it is not listed in the package
lists of any package.
