sudo -h localhost

We all know that sudo complains about unresolvable host names when used 
on a system that doesn't have access to proper DNS and/or its host name 
not being clear. I have not quite understood in which circumstances that 
happens and have happily ever ignored that message, albeit annoying.

I have recently learned that some people use sudo -h localhost to get 
around this message and to keep sudo silent. Reading the man page:

| -h host, --host=host
|         Run the command on the specified host  if  the  security  policy
|         plugin  supports  remote  commands.  The sudoers plugin does not
|         currently support running remote commands. This may also be used
|         in conjunction with the -l option to list  a  user's  privileges
|         for the remote host.

I guess this is taking advantage of undocumented behavior (ths sudoers 
plugin has never officially supported -h). Well, this undocumented 
behavior has changed with the recent security update.

Can sudo offer a different way to get rid of the "can't resolve host" 
error message? Quite a lot of Debian's QA processes run without network.

Greetings
Marc
