Most of the documentation is a snapshot of the old Namesys site (archive.org, 2007-09-29).
There was also a Reiser4 Wiki (archive.org, 2007-07-06) once on pub.namesys.com.
Reiser4 development appears to have stalled and ReiserFS is deprecated and scheduled to be removed from mainline Linux in 2025.
TODO
From Reiser4 FS Wiki
When Namesys was still in place, there was a TODO list (archive.org) to work on to get Reiser4 into mainline. This URL is no more and a lot of changes have been made to Reiser4, the most current TODO list we have is from April 2009 and there're still enough tasks left to be done:
- updated TODO list from 2009-04-25
- updated TODO list from 2008-08-05
- original TODO list from 2007-11-25
- Storage Containers
That being said, reiser4 inclusion seems to be in sight, rumor has it that another attempt will be made in late 2010 or early 2011.
