File 0144-90crypt-Fixed-crypttab_contains-to-also-work-with-de.patch of Package dracut.9455
From 7f4dea242398cc369ff3fecd599faa00d81a522c Mon Sep 17 00:00:00 2001 From: Julian Wolf <juwolf@suse.de> Date: Tue, 19 Aug 2014 16:23:59 +0200 Subject: 90crypt: Fixed crypttab_contains() to also work with device path in /etc/crypttab blkid is not available when this function is called, so block_uuid.map is put into the initrd, mapping block devices from /etc/crypttab to UUIDs. This fixes a bug where udev rules were created by mistake as crypttab_contains() returned false for devices specified by path in /etc/crypttab which resulted in error messages during boot.
