Subject: [PATCH] blscfg: fallback to default_kernelopts if BLS option field
|
|
isn't set
|
|
|
|
If the $kernelopts variable isn't found, then the entry will fail to boot
|
|
since there won't be a kernel command line params set. This makes the BLS
|
|
configuration more fragile than a non-BLS one, since in that case it will
|
|
boot even without a correct grubenv file.
|
|
|
|
So set a $default_kernelopts in the GRUB config file that will be used as
|
|
a fallback if the value in the BLS options field can't be resolved.
