Hi Alberto,

speaking as a packager and a Linux distribution maintainer, I do not agree with
such a change:
1) I would not make an assumption like "if os-prober is installed, there are
several OS" nor that os-prober should be enabled in that case.
2) More generally it is to the package maintainer or local admin what to include
 by default in /etc/default/grub and up to the user to customize it.
3) In case a distribution does not include grub, I would expect a user wanting
to install it to read "info grub" and edit /etc/default grub as he or she sees 
fit.

Best regards,
Didier
