Bug#853234: grub-install ignores errors from efibootmgr

[Steve McIntyre]

Package: grub2-common
Version: 2.02~beta2-22+deb8u1
Severity: serious
Tags: upstream

Hi,

As can be seen in #852513 (for example), grub-install will happily
ignore errors from efibootmgr and claim "Installation finished. No
error reported". This is clearly bogus, and can lead to users with
unbootable systems after upgrades with potentially no warning
up-front (hence the severity).

I've got a small patch prepared locally which I'm about to send
upstream. I'll add a link here shortly to the mailing list archive.

Cheers,

Steve
