thanks for the pointer. After mounting it, I did
sudo chown betom: mnt_fld

cd mnt_fld
ls -la
drwx------  16 betom  wheel        512 Feb 11 12:07 .
drwxr-x---  50 betom  betom       3072 Feb 11 11:47 ..
[...]

which looks ok to me..

but as soon as I unmount and mount again, it reverts to root:wheel

it isn't the end of the world as I will be wrapping the mounting process
with a script, but I just wonder what is the story....
