You can disregard most of that new handbook jail ezjail section.

First of all the current version of ezjail uses the /etc/rc.d/jail 
script method. This method is depreciated in FreeBSD version 10.0 and 
scheduled to be removed in FreeBSD version 10.1 or 11.0. The section 
should have contained a red warning box informing the reader that this 
documentation only applies to Freebsd 10 and older releases.

On the subject of a jails loopback interface. Jails don't have loopback 
interfaces or use them. Sure you can assign one but it's really a 
definition error which the jail(8) program does not issue a error 
message for. All reference to the loopback interface should be removed 
from this section as its very mis-leading to the reader and unnecessary.

I installed bind99 in a jail(8) jail with out any lo1 or 127.0.0.1 ip 
address and it worked just fine.

Adding a password to jails "root" user is a waste of time and effort. 
ezjail already requires the user to have "root" access on the host 
before the "ezjail-admin install" command will function.

Editing the jail's /etc/hosts file and changing the ip address to the 
jails ip address and adding the jailname to the localhost entries is 
totally unnecessary. Jails work fine using the default hosts file.

How can the handbook recommend using a utility tool that has a 
incomplete manual which is missing details about the utilities 
sub-commands.

In my opinion this new section should have never been added to the 
handbook until after ezjail gets updated to use jail(8) and it's manual 
is updated to contain details about all it's sub-commands.
