ReiserFS is a general-purpose, journaled computer file system formerly designed and implemented by a team at Namesys led by Hans Reiser. ReiserFS is currently supported on Linux (without quota support). Introduced in version 2.4.1 of the Linux kernel, it was the first journaling file system to be included in the standard kernel. ReiserFS is the default file system on the Elive, Xandros, Linspire, GoboLinux, and Yoper Linux distributions. ReiserFS was the default file system in Novell's SUSE Linux Enterprise until Novell decided to move to ext3 on October 12, 2006 for future releases.
Namesys considered ReiserFS (now occasionally referred to as Reiser3) stable and feature-complete and, with the exception of security updates and critical bug fixes, ceased development on it to concentrate on its successor, Reiser4. Namesys went out of business in 2008 after Hans Reiser was charged with the murder of his wife (and later convicted and sent to prison). However, volunteers continue to work on the open source project.
Reiser4 is a computer file system, successor to the ReiserFS file system, developed from scratch by Namesys and sponsored by DARPA as well as Linspire. Reiser4 was named after its former lead developer Hans Reiser. As of 2015, the Reiser4 patch set is still being maintained, but according to Phoronix, it's unlikely to be merged into mainline Linux without corporate backing.
Some of the goals of the Reiser4 file system are:
God only knows
God only knows
God only knows
On the surface
Of the one we call belief
Underneath it
Well comes the only thing I've lived without
That's why you must believe me
God only knows why you've been running out
Cause so far the only thing that I've figured out was all of you
Cause God must really hate me
Because I know I don't deserve the things that I've been through
Alone
On the surface we seem plain enough
A little weathered by the work that we do
But underneath it you get tired of running
So you settle in and make sure life gets comfortable enough
God only knows why you've been running out
Cause so far the only thing that I've figuerd out was all of you
Cause God must really hate me
Because I know I don't deserve the things that I've been through
And everything that you are and everything that you were
Is what makes you
And everything that you are and everything that you were
Is what breaks you apart
And everything that you are and everything that you were
Is what makes you
And everything that you are and everything that you were
Is what breaks you apart
Underneath this face I found myself
A little jaded by the things I've seen
But on the surface I get tired of trying
So I settle in and make my life more comfortable for me
And everything that you are and everything that you were
Is what makes you
And everything that you are and everything that you were
Is what breaks you apart
And everything that you are and everything that you were
Is what makes you
And everything that you are and everything that you were
Is what breaks you apart
God only knows why you've been running out
Cause so far the only thing that I've figured out was all of you
Cause God must really hate me
Because I know I don't, I don't, I don't, I don't
(And everything that you are and everything that you were)
And God only knows
(And everything that you are and everything that you were)
And God only knows
(And everything that you are and everythïng that you were)
