Subject: [patch 10/10] incorrect reipl nss name.
Date: Wed, 05 Mar 2008 12:54:42 +0100	[thread overview]
Message-ID: <20080305115715.207905001@de.ibm.com> (raw)
In-Reply-To: <20080305115432.691030908@de.ibm.com>

[-- Attachment #1: 010-nssname.diff --]
[-- Type: text/plain, Size: 1149 bytes --]

From: Hongjie Yang <hongjie@us.ibm.com>

/sys/firmware/reipl/nss/name contains the nss name when defsys or
savesys command has been executed. If the defsys or savesys command
fails the kernel_nss_name has to be cleared since a reipl on that
nss name won't be possible.
