Hi Folks, A couple of recent developments:
First working version of DTrace for FreeBSD has been released: http://bsd.slashdot.org/bsd/06/05/29/1144234.shtml ZFS is being ported to Linux as a FUSE Plugin. This avoids the conflict with GPL: http://blogs.sun.com/roller/page/bonwick?entry=zfs_on_fuse_linux For those who are not familiar with FUSE, it stands for Filesystem In Userspace. Essentially it is a framework that allows filesystem modules to be written as ordinary plugin libraries instead of fiddling with Kernel internals. The framework provides for the filesystem calls in the Kernel to be redirected to va normal userspace library. This allows a variety of interesting stuff like mounting a Website as a filesystem via HTTP-FUSE! There is even a Linux LiveCD that uses HTTP-FUSE to pull filesystem data from from a remote website, if you have a network connection. See: http://fuse.sourceforge.net/ In addition there is an OpenSolaris project to port FUSE to OpenSolaris: http://www.opensolaris.org/os/project/fuse/ Regards, Moinak.
