What I struggle with is that we're calling this a "blobstore". Using
BER to store "blobs" seems kind of pointless especially when we're
talking about exactly three blobs.
I suspect real hardware does something like, flash is N bytes, blob 1 is
a max of X bytes, blob 2 is a max of Y bytes, and blob 3 is (N - X - Y)
bytes.
Do we really need to do anything more than that?
I typically call it NVRAM, but earlier discussions seemed to prefer
'blobstore'.
Using BER is the 2nd design of the NVRAM/blobstore. The 1st one didn't
use any visitors but used a directory in the first sector pointing to
the actual blobs in other sectors of the block device. The organization
of the directory and assignment of the blobs to their sectors, aka 'the
layout of the data' in the disk image, was handled by the
NVRAM/blobstore implementation.
