Hello,
I would like to add some checks and modifications to the Linux command line before booting the OS.
So I am considering writing a grub module which will modify some grub.cfg parameters according to data retreived somewhere on dedicated hardware.
I just realized that it was not possible to write files (on EFI partition or EXT4 partition).
Is there an available patch to allow file modifications ?
I am using grubx64.efi + my module.
Thanks,
Jean-Francois
