Subject: [PATCH] Don't add a class option to menu entries generated for
|
|
|
|
|
ppc64le
|
2019-10-04 15:22:52 +00:00
|
|
|
|
|
|
|
|
For ppc64le a grub config file with menuentry commands is still generated
|
|
|
|
|
even when BLS support is enabled. That's because BLS support was added to
|
|
|
|
|
Petitboot 1.8.0 and any previous version won't be able to parse BLS files.
|
|
|
|
|
|
|
|
|
|
To make the BLS snippets the source of truth, these are used to generate
|
|
|
|
|
the menuentry commands in the grub config file.
|
|
|
|
|
|
|
|
|
|
And to keep it consistent across all ppc64le machines regardless of the
|
|
|
|
|
firmware used, the grub config file is also generated for machines with
|
|
|
|
|
OF that use grub2 and would have BLS support.
|
|
|
|
|
|
|
|
|
|
The BLS snippets created by the kernel package have fields that are used
|
|
|
|
|
to specify the generated menuentry command users and class options. These
|
|
|
|
|
fields are not present in BLS snippets created by OSTree though, so the
|
|
|
|
|
script generating the menuentry commands will add options with an empty
|
|
|
|
|
argument which will lead to grub failing to parse them.
|
|
|
|
|
|
|
|
|
|
We could check if the field is defined before attempting to add those, but
|
|
|
|
|
since the grub2 blscfg module also supports setting these to variables, it
|
|
|
|
|
could lead to an empty argument even if was defined in the BLS snippet if
|
|
|
|
|
the variable doesn't exist.
|
|
|
|
|
|
|
|
|
|
So to make more robust, just don't add a class to the menuentry commands
|
|
|
|
|
generated by the script. It's better to not have a class for the menuentry
|
|
|
|
|
than grub2 failing to parse the command and not populating the boot menu.
