It is beneficial to not have snapshots in-place. With a local directory of

inordinate amount of time and will produce a result you do not expect.

Netapp snapshots are invisible for tools doing opendir()/readdir()
One could simulate this with symlinks for the snapshot directory:
store the snapshot elsewhere (not inplace) and create a symlink to it, in
every directory.

Personally I prefer to have a /snapshots directory on every FS

My users want the snapshots locally in a .snapshot subdirectory.
Because Netapp do it this way - for at least 20 years and we have a
multi-PB Netapp storage environment.
No chance to change this.
