(As Greg pointed out) *If ssh-keygen is available* and I get the warning
by ssh, all I need to do is give the command ssh-keygen -R $hostname
(where hostname can be used from the earlier command via up-arrow or
simple select+middle-click paste) and the host's entrie(s) are removed
form the known_hosts file. Thus for me ssh-keygen has lesser chances of
hosing my known_hosts file than vi or a sed command (which has the added
overhead of using head-cycles).
That is why I think it is elegant, not that I'm forcing others to do
that way too :)
