Bug#862555: linux: please ship efivarfs into efi-modules

[Cyril Brulebois <kibi@debian.org>]

Source: linux
Version: 4.9.25-1
Severity: normal
Tags: patch

Hi,

During the Paris BSP I've discovered that a number of laptops need
firmware but also configuration files which are found in efivarfs.

Please find attached a prospective, untested patch to ship efivarfs
inside efi-modules, so that one has a chance of mounting that special
FS from within d-i.

A thread happened earlier on debian-boot:
  https://lists.debian.org/debian-boot/2016/05/msg00318.html

(cc'ing debian-boot@ and Steve who wanted to get this fixed.)


KiBi.

Subject: [PATCH] udeb: Add efivarfs to efi-modules.

This might be needed to retrieve firmware or configuration bits from
d-i.
