Subject: [PATCH] blscfg: Don't hardcode an env var as fallback for the BLS
|
|
|
|
options field
|
|
|
|
|
|
|
|
If the BLS fragments don't have an options field or if this was set to an
|
|
|
|
environment variable that was not defined in the grubenv file, the blscfg
|
|
|
|
module searches for a default_kernelopts variable that is defined in the
|
|
|
|
grub.cfg file.
|
|
|
|
|
|
|
|
But the blscfg module shouldn't hardcode fallbacks variables and instead
|
|
|
|
this logic should be handled in the GRUB config file itself.
|
|
|
|
|
|
|
|
Also, add a comment explaining where the kernelopts variable is supposed
|
|
|
|
to be defined and what is the process for the user to change its value.
|
|
|
|
|
|
