NILFS is a log-structured file system designed to support fast writing, fast
  recovery times, live snapshots, concurrent read-only snapshot mounts, and live
  file system resizing. Its inodes are managed using B-trees.
The mount_nilfs command attaches the NILFS
    file system residing on the specified special device
    node on the location indicated with node.
  - -ccheckpoint
- Select the checkpoint number checkpoint to be
      mounted instead of the default last one.
- -ooptions
- Use the specified mount options as specified in
      mount(8).
- -tgmtoff
- Set the time zone offset (in seconds) from UTC to
      gmtoff, with positive values indicating east of the
      Prime Meridian. If not set, the user's current time zone will be
    used.
NILFS is a file system developped by NTT and released in 2005 for Linux. Version
  2 is available since 2009. This cleanroom implementation was written by
  Reinoud Zandijk for NetBSD in
  2009, and has first been released as part of NetBSD 6.
This implementation of NILFS was written by Reinoud
  Zandijk.
This implementation currently only supports read-only operation. See
  mount_lfs(8) for an older
  log-structured file system with write support. Also see
  wapbl(4) and
  mount(8) for fast journal-based
  recovery using FFS.
