Sun hints at MacOS X Leopard file system

Sun have hinted that zfs (zettabyte file system) will be part of Leopard. Initially they commented that it would be the default file system, but later changed that to being a file system in Leopard.

ZFS was developed by Sun in 2004 and has been part of Solaris and OpenSolaris. However Solaris has only very recently been able to boot off a zfs disk system. MacOS may also be able to boot off a zfs disk system by the time it launches in October.

ZFS is an extremely flexible system using a 128bit pointers (compared to most file systems 64bit), it supports dynamic pools and journaling.

Steve Jobs may well announce something at the worldwide developers conference that opens today in San Francisco.
