Adding storage to a Jail: strange behavior.

[panz]

I created many ZFS datasets for various storage purposes:

"media" for photos and music
"video" for movies

I've just setup a Plex Media Server into a Jail.

I've added media and video datasets as storage to the Plex Jail.

Both "media" and "video" ZFS datasets have "media" (this is Plex Jail's "media" folder, NOT my ZFS dataset) as destination into the jail.

I expected that no data is written by the jail into ZFS datasets, but now I find an (empty) video folder into "media" ZFS dataset! :(
