missing string in po file?

Hi,
lately we got bug report #394505 on the Italian translation. One of the
problems pointed out is the missing translation of "Support for
automatic installs". I browsed the d-i repository and found this string
only in file "debian/control" for package "auto-install".

How should we translate it?

Thanks,
Giuseppe
