Hope the last quescion what is not really not clear until the end to me 
Folowing Configuring fstab based NFS share mounts
it is is written:
"if everything is fine, you can add the NFS mount as a media source to Kodi. The path were the NFS mounts are found will always be this one:
/mnt/
SO do I understand good, that then I enter (in my case):
sudo mount /mnt/Transmission
and
ls /mnt/Transmission
And when I see all my files in share folder (in my case Trasmission) through SSH.
So next step:
I have to go to GUI of OSMC and through Network file system (NFS) add my share (Transmission). But how can I be sure that it is really conected using FSTAB , but not regular NFS share method?
This is what I do not understand? Is any way to check?
A little bit confusing, because befoure I entered correct FSTAB line, I anyway could see my share “Transmission” through GUI OSMC Network file system (NFS)
