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.
Maybe it should take hints how to interpret variable values, or have format option akin to printf.
Thanks,
Mat

Hi,I'm the author of that patch. No, it was never merged into the tree. As
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
far as I know, there is no equivalent functionality; GRUB does not support
this feature.
Thanks,
Mat
