Tying a filesystem to a particular storage technology and thus losing the ability to move the filesystem between storage devices doesn't seem to be a desirable feature in any filesystem from a user perspective.

Tying it to the technology can make sense if your whole purpose is to exploit that technology to its fullest. If you later decide you want to move the filesystem back to your floppy disk array, you'll need to do a copy anyway, so changing the filesystem type shouldn't be a big deal. How often do you move a filesystem image between different media types?

Now the inability to move to another system with a different number of processors...that seems like a problem...

Particularly given that we support dynamic CPU plugging/unplugging...

Corbet, what RAID levels does your floppy-array support?

I would imagine it can do RAID 5 but you may be occasionally prompted to insert disc 2.
