Hello,
with reference to bug id #4852821: user undo
I have implemented a basic prototype that has the current functionality:
1) deleted files/directories are moved to /your_pool/your_fs/.zfs/deleted
Unfortunately, it is non-trivial to completely reproduce the namespace
of deleted files: for now, deleting "/foo/bar" will result in
".zfs/deleted/bar".
2) As a result of 1, deleted files move out of .zfs/deleted in FIFO.
Ie. if you remove /foo/bar twice, the most recent copy will be the one
remaining in .zfs/deleted.
3) If another user deletes /foo/bar, and you try to delete /foo/bar,
you will be denied permissions. Again, this is due to namespace
clashes.
How about appending the decimal inode number to the file name?
Anything that attempts to append characters on the end of the filename
will run into trouble when the file name is already at NAME_MAX.
