Creating a jail mount point with CLI?

[Daisuke]

Can I create a jail mount point, say from ssh instead of GUI? If yes, please let me know the command. This will allow me to automate certain jail actions.

iocage fstab -a jailname /mnt/tank/apps/whatever /config nullfs rw 0 0

Where /config exists in the jail as an empty directory, so maybe you could do this first:
iocage exec jailname mkdir -p /config
