From b53510e0d09d8c550a123fdca8467ff325c6f68a Mon Sep 17 00:00:00 2001 From: Adam Van Ymeren Date: Sun, 11 Jun 2017 13:01:31 -0400 Subject: [PATCH] file-systems: Handle EIO error in 'ENOENT-safe' as well. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Trying to boot GuixSD when an audio CD is in the drive will die with an "input/output error" when trying to read the superblock from the cd drive. This patch catches and warns in this case rather than dying. * gnu/build/file-systems.scm (ENOENT-safe): Handle EIO.
