Subject: [PATCH] blscfg: Lookup default_kernelopts variable as fallback for
|
||
|
|
options
|
||
|
|
|
||
|
|
The 10_linux script sets a variable that contains the kernel command line
|
||
|
|
parameters. This is done so the entries will still have a kernel cmdline
|
||
|
|
defined even if the grubenv can't be read.
|
||
|
|
|
||
|
|
But older versions of the script used to set a default_kernelopts variable
|
||
|
|
while newer versions just sets the kernelopts, which is what's defined in
|
||
|
|
the BLS snippets.
|
||
|
|
|
||
|
|
The blscfg module needs to keep looking for the default_kernelops since it
|
||
|
|
may be that a user doesn't have a grubenv file and has an older grub.cfg
|
||
|
|
that sets this variable instead of kernelopts.
