Restoring and snapshots

[Andrea Venturoli]

Hello.

When I'm doing backups/dumps of ZFS filesystems (with whatever tool), I 
use snapshots.
So, suppose I have the following datasets:
/etc
/usr
/usr/local
/var

I'll snapshot them and back up
/etc/.zfs/snapshot/snapname/
/usr/.zfs/snapshot/snapname/
/usr/local/.zfs/snapshot/snapname/
/var/.zfs/snapshot/snapname/

Then I'll get the same directory structure when restoring.
Any idea how to easily remove the .zfs/snap and go back to the original 
tree?

I tried writing a few lines of script, but I found out that's not so 
easy (due to directories which must overlap, spaces in file names, etc...).

Any hint?

  bye & Thanks
