FreeBSD-11 - /etc/fstab

I am experimenting with installing iDempiere on a jail called
hllidempiere created with ezjail.  As part of the prerequisites
OpenJDK is required.  When installed in the jail the OpenJDK pkg says

This OpenJDK implementation requires fdescfs(5) mounted on /dev/fd and
procfs(5) mounted on /proc.

If you have not done it yet, please do the following:

	mount -t fdescfs fdesc /dev/fd
	mount -t procfs proc /proc

To make it permanent, you need the following lines in /etc/fstab:

	fdesc	/dev/fd		fdescfs		rw	0	0
	proc	/proc		procfs		rw	0	0

Now, there is no /etc/fstab in the jail itself.  However on the host
system there exists: /etc/fstab.hllidempiere.  Checking
/usr/local/etc/ezjail/hllidempiere I see that these flags are set:

export jail_hllidempiere_mount_enable="YES"
export jail_hllidempiere_devfs_enable="YES"
export jail_hllidempiere_devfs_ruleset="devfsrules_jail"
export jail_hllidempiere_procfs_enable="YES"
export jail_hllidempiere_fdescfs_enable="YES"

So, I believe that I should be able to perform the requisite file
system mounts. What I am not clear on is how to add these file systems
to the jail's fstab so that they are automatically mounted whenever
the jail starts.  I attempted to add these commands to
/etc/fstab.hllidempiere but this had no evident effect.

How is this done?
