Looking at function getyn() posted by Bill Hacker I
eventually understand what's wrong. Code - the universal language...
So, really, the best thing that we can do is to introduce a
--force-slave-pfs-creation switch and replace the getyn() call in
cmd_mirror.c by a simple if (ForceSlavePfsCreation...). I like this
more than the original approach (using ttys), as it is usable from
within scripts.
Agree that.  I still like the countdown as in cmd_pseudofs.c

A Ctrl-c DOES work, and five second longer setup time is no show-stopper.

While we are working on this, we could replace all
interactivity in hammer utilities with optional command line switches.
So the strategy could be: first look if there is a switch specified, if
not, fall back to /dev/tty, if this fails, assume NO.
I do not like a command line switch "-f", which means anything
(including force). It's too easy to mix it up with "-f" meaning
"--file". Think about doing some admin work late after midnight, and
your fingers go again faster than your brain; while a "rm -rf" on a
Hammer FS would give you a second chance, a mixed up "hammer
mirror-copy -f" would probably not :). I really would like to see a
--force here (or a more specific one).

Agree single-character options are impossible to keep straight. And 
scripts don't care much anyway.

How about these ones:

-jfdi		--just-fucking-do-it

-bfbim		--brute-force-and-bloody-ignorance-mode

(my coding style, BTW. forth breeds that sort of um.. 'elegance')		

;-)
