Bugzilla Bug 120471

Under certain circumstances, mine where ssh + chroot, if that mean something.

"dialog" program, widely used inside the script, return an error "cannot open
tty-output", like it was a terminal-less connection, the solution for me was to
change all the occurencies where dialog is called in a subshell from:

--- from ---
USER=$(dialog --stdout \
    --backtitle "Please choose a username and password for the initial user." \
    --inputbox "Username:" 0 0 "admin")
RESULT=$?
--- from ---

to 

--- to ---
dialog --output-fd 3 \
    --backtitle "Please choose a username and password for the initial user." \
    --inputbox "Username:" 0 0 "admin" \
    3> "/tmp/${tmpfile}"
RESULT=$?
USER=$(< "/tmp/${tmpfile}" )
--- to ---

may be other are affected, or is this one a misconfiguration issue of this
particular box ?

I was unable to reproduce this. Can You provide me more information, for
example if it happened more than once?

it's a "corner case" it happen if "dialog" cannot find/use /dev/tty* feel free
to fix as wontfix

Fixed in app-admin/zope-config-0.6.
Thanks
