Subject: [PATCH] system: Avoid using device paths in <menu-entry> device field.
Date: Thu, 3 Nov 2016 06:10:28 -0700 [thread overview]
Message-ID: <20161103131028.7984-2-cmmarusich@gmail.com> (raw)
In-Reply-To: <20161103131028.7984-1-cmmarusich@gmail.com>
From: Chris Marusich <cmmarusich@gmail.com>
This fixes a regression introduced by
1ef8b72a7f87afe7cffe52393d99e1b14e4770e1, in which we would incorrectly use a
device path in a label-based grub root search command, e.g. 'search --label
--set /dev/sda4'.
* gnu/system.scm (grub-device): New procedure.
(operating-system-grub.cfg, operating-system-parameters-file): Use it.
(read-boot-parameters): Handle device paths correctly.
