Yesterday Phoronic posted an article, An Update On Reiser4 For The Mainline Linux Kernel. Truth be told, I kind of forgot about the file system. It seemed to fall into the far background of Linux file system development as more light was shed upon Ext4-fs and the upcoming Btrfs. I am kind of surprised that it still hasn’t been included into the mainline Linux kernel yet. But I was surprised to see Phoronix report on it. They must of had nothing else to report on.
So, who is really waiting for Reiser4? And even if does boast interesting features that Ext4 does not, how can it compete with something like Btrfs? I mean, c’mon, volume creation, snapshots, data compression, etc. Don’t get me wrong. The approach taken with the Dancing B*-trees are an interesting concept and do aid in the file system’s ability to retain atomicity and stability. But it is difficult to see a future for Reiser4 when (as the article mentions) no one is supporting it. ReiserFS v 3 got a major boost from SUSE.
