Hi,

currently, /usr/lib/hurd/setup-translators contains the following snippet:

[ -r /var/lib/random-seed ] || date > /var/lib/random-seed 2> /dev/null

This means that the contents of /var/lib/random-seed will differ every time the
script is run. This is undesirable when the script is run in context of
producing bit-by-bit reproducible installation media or bootable system images.
The patch at the end of this mail fixes the problem.

Thanks!

cheers, josch
