This was the error on screen during dist upgrade from Trusty Tahr, for
convenience:
/etc/kernel/postinst.d/x-grub-legacy-ec2:
Searching for GRUB installation directory ... found: /boot/grub
Searching for default file ... found: /boot/grub/default
Testing for an existing GRUB menu.lst file ...
Public bug reported:
This seems wrong - boot device is mission-critical.. a uuid is (in my
opinion) far more reliable than using a serialized drive name (which
could change based on disk order in the system, e.g. if the hard drive
were moved to another SATA or SAS port).
ProblemType: Package
