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.
