Hi Ludo,

I don't understand why this current-output-port stuff is somehow passed on =
to
forked processes in the first place (why does cryptsetup care what I do
to guile variables?).

scheme@(guile-user)> (current-output-port (%make-void-port "w"))
scheme@(guile-user)> (system* "ls" "/")
scheme@(guile-user)>

WTF?

It wasn't my intention to inherit them as file descriptors... also, for gui=
le
buffering ports, how does it inherit those as file descriptors?  Will it st=
ill
do the custom line buffering that shepherd does, also when a child process
writes there?
