And ZFS important for the desktop? What a nonsense ...
Well, ZFS does seem already to have easier administration tools than the Linux Partitioning/RAID/LVM/EXT3 stack.
There is no reason that all those layers could not be easily controlled through a simple gui. But I'm beginning to despair of it ever happening. It's not like any one of those layers is new. And still, adding a new drive to an existing filesystem is rocket science.
It's not just that you have to drop to the command line to do it. It's that you have to drop to the command line and make the new drive a physical volume, add the physical volume to the volume group, expand the logical volume, and then online resize the filesystem. Oh, and you'd better do all that by UUID or label, and not device name, because you are not guaranteed that the device name will remain constant. Simple, isn't it?
I envision plain old end users being able to just plug another USB drive into their machine, and have it simply added to their existing filesystem.
They can already do this with RAM. Just plug it in and they have 2GB whereas they used to have 1GB.
They should be able to do the same with storage.
Again, there is no reason we *can't* do this in Linux. But it looks to me like ZFS has at least made some progress toward simplifying FS administration for people who don't happen to be experts.
Regarding your other claim. I tend to agree, as things stand today.
But, I suspect that composited desktops will gain some actual value once the silly and useless effects are dropped (retaining any features which are actually useful that may sift out), more cards support them, stability increases substantially, and they are considered mundane enough that no one talks about them any more. (And users come down hard on anyone who tries to reintroduce silliness like wobbly windows).
But I suppose this is not really the place to have that discussion. Edited 2007-04-07 03:09
