Subject: bug#27331: [PATCH] Handle EIO error in ENOENT-safe as well.
Date: Sun, 11 Jun 2017 13:01:31 -0400 [thread overview]
Message-ID: <87y3syqx04.fsf@vany.ca> (raw)
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.
