Hi SevenBits,
Thanks for letting me know. Out of curiosity, any particular reason why
this patch did not get merged? It looks to be a useful feature.
First, this patch was reverse patch :)
I am not convinced making it easy to set EFI variable from within GRUB
is good thing, because there are known reports about systems rendered
unbootable by writing too much into EFI flash. What is your use case
that absolutely requires setting EFI variables? How are you going to
implement it on other platforms?
Reading does not harm and may be useful, but then it should provide
generic interface to access arbitrary vendor namespace, not only EFI
global variables, and handle arbitrary binary data, even if initial
implementation handles only subset of them. Once someone starts to use
it changing it will be much more difficult.
May be it should take hints how to interpret variable values, or have
format option akin to printf.
Thanks,
Mat

Hi,
Searching through google, I see there was an email thread to add a patch
for getting and setting efi variable in GRUB2.
https://lists.gnu.org/archive/html/grub-devel/2013-11/msg00328.html
However, looking at the tree, it doesn't look like this patch was added,
am I missing something? Does anyone know if we have command to get/set efi
variables in GRUB2?
http://git.savannah.gnu.org/gitweb/?p=grub.git;a=tree;f=grub-core/commands/efi;h=005fd2efc9a2eede2a1eb1cab8081c360219107b;hb=HEAD
I'm the author of that patch. No, it was never merged into the tree. As
far as I know, there is no equivalent functionality; GRUB does not support
this feature.
Thanks,
Mat
