Personally, I think we should keep all of those tools enabled, and
simply fix the installation path, especially since inetutils is often
the only one doing "weird" things, and all of the other packages agree
on the location for all tools

First, for the "Found same path" cases above, I believe the solution is
fairly easy: just make sure inetutils depends on the relevant packages
so that they get overriden. For busybox it's easy, we always want the
inetutils tools to override the busybox one. For the other packages, it
might need a little bit more discussion as it's not immediately clear
which package has the "best" implementation for each of the tools.

Now, for the "Found same filename" cases, the situation is quite clear:

 * dnsdomainname: both busybox and net-tools install it to /bin,
   inetutils is the only one to choose /usr/bin. So the solution is to
   move it to /bin in inetutils.

 * ping: both busybox and iputils install it to /bin, so same solution
   as above.

 * hostname: both busybox and net-tools install it to /bin, so same
   solution.

 * ifconfig: both busybox, and net-tools install it to /sbin, so same
   solution.

 * syslogd: both busybox and sysklogd install it to /sbin, so same
   solution.

You can also try to pass --exec-prefix=/ in INETUTILS_CONF_OPTS and see
if it improves the situation.

Best regards,

Thomas
