Bug#921702: grub2 2.02+dfsg1-10 ignores user input at debconf prompts

[Steve Langasek]

Package: grub-pc
Version: 2.02+dfsg1-10
Severity: important

The changes to ucf handling in grub2 2.02+dfsg1-10 result in any changes the
user tries to make to their config via dpkg-reconfigure being ignored.

 - user edits the kernel commandline through debconf prompt
 - postinst script applies the change to the "new" /etc/default/grub via a
   tmpfile
 - /usr/share/grub/default/grub is unchanged vs
   /var/lib/grub/ucf/grub.previous
 - UCF_FORCE_CONFOLD=1 is passed, which means the new config in the tmpfile
   is completely ignored in favor of the copy already in /etc/default/grub
