Pushing Reiser4 Is "Not Of High Priority"

Main purpose of reiser4 was preparation for reiser5: Semantic data structuring per filesystem. This would have been the ground setting where ai could florish.
On an google tech video I saw a talk about his vision: Like the container technology slim lined transportations by vanishing all media frictions, reiser4 can deliver the true unix philosophie as a filesystem: Everything is a file, even file attributes!

About btrfs
I want reiser4 for 3 reasons..
* Compression (just think of all the header files in /usr/include and /usr/share/doc)
* Not CoW (Copy on write)
* btrfs is backed by Oracle. I really don't trust Oracle
Ext4's creator said that his fs is just something to use while waiting for btrfs.

1) most large file formats incorporate compression,
2) you can apply a filesystem compression overlay.
FYI: those two paths, on my machine that I'm sitting at right now, consume under 1 GB of disk space. At last I checked, you could grab a 1 TB disk for about... $50. How much is this REALLY going to help you? Right... not worth the effort.

look at btrfs; it has a number of the same design ideas that reiser3/4
had --- except (a) the filesystem format has support for some advanced
features that are designed to leapfrog ZFS, (b) the maintainer is not
a crazy man and works well with other LKML developers (free hint: if
your code needs to be reviewed to get in, and reviewers are scarce;
don't insult and abuse the volunteer reviewers as Hans did --- Not a
good plan!).

This point of view was even popularized by games which installed their data compressed in .pak files rather than uncompressed. People then unpacked those files and noticed that loading times increased by a quite big amount. Compression was making disk accesses faster. Executable packers like UPX also resulted in lower loading times when running big executables.
So compression is a cheap way to increased disk I/O speed.Last edited by RealNC; 18 October 2011, 01:52 PM.

1 disk space not a matter of todays
2 CoW even better for lifetime of coming ssds, also I don't know how it is possible to edit a 4Gib video
3 mainline kernel modules are havy guarded, peer reviewed.
I wish we had reiser5 semantics in place:
The real potential of kde assistive features could florish, not having nepomuk and strigi to run crippled databases
