See what I wrote previously:

This is because

cmd ln -f -s fd/0 stdin

does not take care of the case when /dev/stdin already exist. This
doesn't have any consequence, but could be fixed by checking whether the
symlink already exists.

The native-install step of crosshurd does run the hurd package scripts,
so that shouldn't be a problem.

Again, we are supposed to add the diversion on installation only, to let
the admin change the configuration.
