Yes subtree snapshots would be interesting but for my use case each jail can have it's own PFS so don't really need subtrees. Also I am not sure if I create a pfs then mount it in the tree with it's root as a directory and I am able to snapshot part of it might be a bit confusing. One think I found possible is to delete a PFS while I have it mounted in the directory tree. I got errors on trying to delete the tree after I had deleted the PFS, but not when I did the hammer2 pfs-delete command I am guessing there is no direct link between the two. How can I view history on a file? There is no hammer2 history anymore? On a maybe different not I would really like how to get rid of the rm prompt :) . Cheers, George
