It lacked support for snapshots. It was removed from FreeBSD and OpenBSD, but still lives on in [[NetBSD]]. * [[Plan 9 from Bell Labs\|Plan 9]]'s [[Fossil (file system)\|Fossil]] file system is also log-structured and supports snapshots. * [[NILFS]] is a log-structured file system implementation for [[Linux]] by [[NTT/Verio]] which supports snapshots. As of May 2007, it is still in [[software release life cycle#Alpha\|alpha]] and not ready for production use.
