Re: [PATCH 2/2] pstore: update the policy of the UEFI-based backend

[Matthew Garrett]

I don't think this is reasonable. EFI variable space is a shared 
resource. We have no idea what the failure modes of entirely filling it 
would be. If we're going to store multiple records then at the very 
least we need to use QueryVariableInfo() to identify how much space 
there is left, and if it's a 2.1 or later system then we ideally need to 
store these as EFI_VARIABLE_HARDWARE_ERROR_RECORD rather than just plain 
runtime variables. The reason the current implementation doesn't do that 
is that there's still hardware floating around that implements EFI 1.10 
rather than UEFI 2.0
