From 7527b90c886e0c950f4a533fbb4eefb3714a5f9a Mon Sep 17 00:00:00 2001 From: Zhiguo Deng Date: Fri, 16 Oct 2015 04:04:34 +0200 Subject: [PATCH] Check rd.zfcp= format in dracut hook:cmdline process stage When using rd.zfcp= parameter in generic.prm file, wrong format parameters will prevent the zfcp driver to add the correct SCSI disk. dracut should die when a wrong rd.zfcp= parameter supplied.
