There are numerous jail management methods.  ezjail was and still is 
popular.  The warning message has annoyed enough people that there is 
actually a sysctl to disable it now.

qjail is a forked version of ezjail. It is strongly recommended by the 
person who forked it.  There is a long story here, and a search of the 
mail archives will result in some interesting reading.

iocage is a valid choice, and probably the most popular new jail 
management method. Of course, there are two versions of iocage, one in 
shell and one in Python.
