Subject: Unquote parameters written to Xen EFI config file
|
|
References: bsc#900418
|
|
Patch-mainline: not yet
|
|
|
|
The GRUB_CMDLINE_* value is copied verbatim to grub.conf, so it is first
|
|
parsed by GRUB2 before being passed down to the kernel. OTOH Xen EFI loader
|
|
takes the config file options verbatim. This means that any special GRUB2
|
|
syntax must be evaluated when generating that file.
|
|
|
|
Of course, some things are not even possible (e.g. substituting GRUB runtime
|
|
variables), but let's call them known limitations.
