Well, Mike, I don't think I can put it more strongly.  If you are
insistent about making this change, I cannot stop you.  I wish you
would not.

If it is not gratuitous, pray tell what benefit this change will
bring.  It will certainly snag a minority of folks, and that makes it
a bad idea as far as I am concerned.

We try very hard _not_ to break things.  We break things only when
there is a compelling reason to break them.  Not because we just feel
like it.

As I implied in an earlier message, I would prefer that it never be
merged to 4.x.

I don't track RELENG_4_5.  I _maintain_ the RELENG_4_5 and other
security branches.

Yes, it is worse.  It probably will not happen until the run
application X --- perhaps an ICQ client, or an FTP server, or
whatever.  It will fail, and for some people it will cost time to
determine the cause and to repair it.  This is not /so/ bad for
someone tracking -STABLE, except that the whole problem can and should
be avoided.

BSD has used the low range ports ``forever''.  There is absolutely no
time-critical reason to change the default now.


I don't think I'll be posting on the issue again, as the length of the
thread will soon be disproportionate to the subject's importance, if
it isn't already. :-)
