So far:

it's a 2048 byte superblock (we insist on having 8192 bytes).
the old_flags field isn't known and we try to intrpret it.
the sblockloc field isn't known and validation fails.
the maxsymlinklen field isn't known and the 'value' triggers a panic.

fsdb doesn't care, so I can use it to look for files and retrieve the
content.
