NILFS 2.0.0-testing was released. It is our pleasure to announce the release of the NILFS 2.0.0 (-testing). The Garbage Collector (Cleaner) with numerous snapshots is implemented to NILFS. Download and try it!
This is a testing release, you may meet unexpected BUGON, losting files, etc.
If you meet an error such that /sbin/nilfs_cleanerd: error while loading shared libraries: libnilfs.so.0: cannot open shared object file: No such file or directory, could you type "/sbin/ldconfig /usr/lib" or get utils tarball again? Sorry for your inconvenience.
-- Jun 13, 2007 JST.
We will hold a BOF session in Linux Symposium Ottawa June, 2007, titled "Filesystem support for continuous snapshotting". Please join to discuss if you are general kernel hacker or you're interested in snapshotting.
-- May 24, 2007 JST.

We start testing the NILFS on x86_64 architecture. Several data structures on disk had been `packed' to keep compatiblity between 32bit and 64bit platforms. If you already have a NILFS file system partiton on x86_64, could you format the partition again?
Sorry for inconvenience.
-- Mar 8, 2006 JST.
