Another question...
Should the core pstore fail to unlink partitions that don't have an ->erase callback ? IE. Why would you let anyone erase the OFW common partition for example ? That means that userspace tools can no longer manipulate it but we certainly don't want to remove it from the nvram itself.
That leads to a deeper concern. Looking at how efi-pstore works, it looks like they create a file for each var.
This looks like something valuable we could do for something like the common partition since typically it's made of name,value pairs.
However, pstore is a flat space, while we have patitions which themselves can be organized in name,value pairs (some at least)
I wonder if it's time to introduce pstore directories... Or do we stick to our special tools to interpret/change the name,value pairs ?
Also do we want to add an ability to resize partitions ? Possibly based on how much is written to them ?
Cheers, Ben.
