i clearly understand that, and will manage my script(s) accordingly.
thanks. :-)

fwiw, the snippet i attached is a part of a larger, expect-based
script i use to roll-out gpg "key packages" to new employees.  as
'batch' support is only, currently provided (afaict ...) for gen-key,
i simply use expect (even though i think it's a major pita!) to be
consistent across all my other script functions.

atm, there's no other convenient full-autommation option that i'm
aware of; and, again, yes, i know it's 'upgrade fragile'.

thanks.
