Yes, if it's local. Just use df -n $path and it'll spit out the filesystem
type. If it's mounted over NFS, it'll just say something like nfs or
autofs, though.

I can think of a different feature where this would be useful - storing virtual
machines.
With an automatic 1fs per folder, each virtual machine would be stored in its
own filesystem, allowing for rapid snapshots, and instant restores of any
machine.
One big limitation for me of zfs is that al

Whoah! Seriously? When did that get added and how did I miss it?
That is absolutely superb! And an even stronger case for mkdir creating

Because it means you can create zfs snapshots from a non solaris/non
