 ====== To Do ======
-  * create ZFS dataset with 20% reserve quota
+  * create ZFS dataset with 20% reserve quota <code bash>zfs create -o quota=300G -o mountpoint=/jails zroot/jails</code>
-    * **zfs create -o quota=300G -o mountpoint=/jails zroot/jails**
+  * replace hardcoded jail paths with variable<code bash>export jail=/jails/BASE
+echo $jail</code>
+  * add UTF8 configuration to BASE jail
+  * need to create alias for jail ip on hosts network interface during jail creation.
+    * using ''ifconfig'' for one-time use <code bash>ifconfig igb0 alias 10.0.0.92 netmask 255.255.255.0</code>
+    * permanent using ''rc.conf'' <code bash /etc/rc.conf>ifconfig_igb0_alias2="10.0.0.92 netmask 255.255.255.0"</code>
