Bug#514705: +1 (warn before making system unbootable).

[Charles Plessy]

+1

Something like: "You are upgrading from an experimental package and your system
will probably become unbootable" would save a lot of time from many people.

Sure "It's my fault" to have tested grub2 in the past and forgot to remove it,
but like many persons, I did not expect that upgrading to Lenny would break my
system…

Have a nice day,
