This doesn't log anything because executing 90console actualy spawns
debconf/frontend to execute the script.

So I inspected things by hand:

1) readlink on /proc/$(pidof debian-installer)/fd/0 evaluates to "/dev/console"
2) "mapdevfs" returns /dev/console

This is hitting the "Pass unknown devices without changes" path
in debian-installer/devfs.c:di_system_devfs_map_fron

This code seems to assume that the installer will have the underlying
device openned, but instead it is /dev/console which it will have.

Code needs to be added, somewhere, to translate /dev/console to
whatever the underlying device is.  Or to detect the serial console
in some other manner.
