Using template of a basejail to create new jail

[Vinoth Deivasigamani]

I created a jail of type basejail and name "test_template". Then I set the template attribute to yes. I created a new jail called "test" based on the template "test_template". I could not start the newjail. It looks like the reason is that the new jail's (name test) fstab does not have the nullfs entries pointing to the RELEASE. However, test_template's fstab has those entries. What am I doing wrong? Here are some, and outputs to illustrate what I'm describing here:
