efi_no_storage_paranoia

[Péter Prőhle]

Due to an EFI implementation error spreaded wide a half or full decade ago, I need

        kernel parameter "efi_no_storage_paranoia" during the (grub efi) installation

for my Lenovo Edge E125 (ThinkPad), --- and according to internet quite a lot of bit older, first generation of EFI motherboards and laptops are also effected in exactly the same way.

The usual symptom is that:

        warning: Cannot set EFI variable Boot000A.

        warning: vars_set_variable: write() failed: No space left on device.

        error: failed to register the EFI boot entry: No such file or directory.

Additional symptom is that after RE-FLUSHING the bios for the same version,

        the first efi install is successful, free from this error

        but all the later efi installations have this error

The reason is that each of this early EFI bios impementations report a

        NV-storages usage over 50%, and

        kernel without "efi_no_storage_paranoia" does not want to register the fresh install

Each of the ubuntu desktop, ubuntu server and debian install cd/usb resource is affected with this error, and each of these

        works without error, if I add the kernel parameter "efi_no_storage_paranoia"

at boot time, using the edit function of the grub.

Suggestion:

        there should be an additional grub menu item, offering this small extra feature

Perhaps there could be an extra safety measure, that the installer rejects to make use of this possibility, if there is no linux item among the efi-variables what can be deleted. I.e.: this extra possibility should be allowed only if the registration of the new item can replace one of the previous linux items of any distribution, or at least an Ubuntu or Debian.
