  No it's on by default, and easy to change in /etc/default/xinetd. But
I do believe (and there was an RC open on xinetd for that, and I agree
about it) that it being off by default is wrong, because xinetd cannot
document it's a proper inet-superserver without doing that. If as an
administrator you disagree, you can change that anytime.

  Since xinetd conflicts with inet-superserver it's the sole one that
can honour /etc/inetd.conf.  The final plan is to let update-inetd work
on both the xinetd configuration and /etc/inetd.conf. This way, here are
the possible scenarios and administrator can use:

(1) only honour /etc/xinetd* files, by disabling compat mode
    altogether.
(2) work in compat mode, with the (probable, I did not checked but it's
    likely) drawback that a service "disabled" in the /etc/xinetd* and
    enabled in /etc/inetd.conf will probably be run.

  There are 2 ways of not falling in the (2) trap:
  - either always use update-inetd to enable or disable services (once
    it'll support xinetd configuration files btw)
  - or me patching xinetd if it behaves like I fear it does to ignore
    services from /etc/inetd.conf that are filed under the same name
    than in /etc/xinetd*. I believe it to be the proper approach, I'll
    try to write a patch asap.
