More tests on Xubuntu. root@xubuntu-vm:~# zfs get mounted rpool/ztest NAME PROPERTY VALUE SOURCE rpool/ztest mounted yes - root@xubuntu-vm:~# zfs list | grep rpool/ztest rpool/ztest 196K 14.8G 196K /ztest root@xubuntu-vm:~# zfs get mountpoint rpool/ztest NAME PROPERTY VALUE SOURCE rpool/ztest mountpoint /ztest inherited from rpool root@xubuntu-vm:~# In Xubuntu, the mounted property is 'yes', which is what I would expect since I can create a file on it. This difference maybe has something to do what is happening. Looking at this from a beginner point of view, Linux makes sense but not FreeBSD, so if it is a feature rather than a bug, I cannot understand its logic!
