Subject: Check rd.zfcp= format in dracut hook:cmdline process stage
X-Git-Tag: 044~19
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=7527b90c886e0c950f4a533fbb4eefb3714a5f9a;p=thirdparty%2Fdracut.git

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.
