Solaris has long claimed superiority in the area of filesystems. It' ZFS technology makes ext3 start to look antiquated (although ext3 is more mature). Andrew Morton has long since argued for the need of a new 'from scratch' filesystem to replace the aging and in his words 'crufty' codebase of ext3. Various filesystems have come and gone and for quite sometime many in the Linux community thought Reiser4 would be that filesystem, but alas it was not to be (at the risk of offending someone I will spare the details).
"However Oracle it seems will be the unlikely hero, as it's skunkworks develop a next generation Linux Filesystem named Btrfs..."
