I don't think these affect blkid or similar programs even if additional fields may be required in the superblock. One my concern about the automated recognition is too short magic field of nilfs. I think those tools will need to confirm the checksum in addition to the magic field. If I have a chance to reorganize the superblock, I would like to make it longer and adjust some other fields. But I will not do so for the above features. > I'd happily write patches for those utilities to add nilfs recognition > if you think there is a stable fingerprint that can be recognized. > > Thanks, > -Eric Thank you for the proposal! I'm grateful if you could do so. I think the time when we drop the experimental flag from Kconfig is the time.
