Required Programs to use NILFS
NILFS consists of a kernel module and utility programs (nilfs-utils or nilfs-tools). To use NILFS, both are needed.
The kernel module of NILFS (referred to as "nilfs2") is included in Linux kernel since version 2.6.30. Please use the one included in your Linux distribution, or download and build the source code of an upstream kernel, which is available at https://www.kernel.org/. For the upstream kernel, using a recent stable kernel or a longterm kernel is recommended.
For CentOS or other RHEL clones, using the stand-alone nilfs2 module available below is recommended. The source code of this module is also available for part of the upstream kernels. If the version of your kernel is not new but supported by the stand-alone module, then we recommend to use it instead.
For the utilities, please use the one included in the distribution, or download and build the latest source package available below. For instructions on how to build the source package of utilities, please see the enclosed README file.
