First, if you haven’t already done so, create a debian 7 template jail. See my previous post ‘Debian 7 Wheezy Installation in FreeBSD 10 Jail‘ if you need assistance on doing so…

Clone your debian-7-linux template…

root@host:/ # zfs clone zpool/usr/jail/.debian-7-linux@p0 zpool/usr/jail/unifi-video

Append the new jail configuration to ‘/etc/jail.conf’

... append to the bottom ...
# UBIQUITI UNIFI VIDEO NVR
unifi-video {

  interface = "ge0";       # confirm the name of your interface...
  ip4.addr = 192.0.2.201;  # set to an ip address thats routable...

  exec.start = "/etc/init.d/rc 3";
  exec.stop = "/etc/init.d/rc 0";

  allow.mount;
  mount.devfs;

}

Create Jail fstab: ‘/etc/fstab.unifi-video’

sys             /usr/jail/unifi-video/sys               linsysfs        rw                      0 0
proc            /usr/jail/unifi-video/proc              linprocfs       rw                      0 0
tmpfs           /usr/jail/unifi-video/run               tmpfs           rw,noexec,nosuid        0 0

Start the Jail:

root@host:/ # service jail start unifi-video

Start a shell in the jail:

root@host:/ # jexec unifi-video /bin/bash

Retrieve the lastest debian package from ubnt.com

root@unifi-video:/# cd /root/

Change ownership on ‘/var/cache/unifi-video’

root@unifi-video:/# chown unifi-video:unifi-video /var/cache/unifi-video

Add unifi-video specific tmpfs mount manually to ‘/etc/fstab.unifi-video’ on host system:

# CUSTOM TMPFS FOR UNIFI-VIDEO JAIL
tmpfs           /usr/jail/unifi-video/var/cache/unifi-video     tmpfs           rw,noexec,size=15%,mode=0777,uid=unifi-video 0 0​​
