When learning a non-trivial subject, RTFM and STFW can require a lot of 
effort -- especially the latter, as the WWW is full of incomplete, 
obsolete, and contradictory information.

I am willing to pay a reasonable price for a printed book that contains 
current information, organizes it, and presents it in a rational order. 
Lucas writes such books, and I own eleven of them.

I do not recall ever encountering an error when entering an example from 
a Lucas book.  (But, I have not entered every command from every book.)

When I wanted jails for my SOHO server, I read Lucas and choose the 
jail(8) option.  My server is running 24x7 without issues.

I believe I attempted ezjail for a second server, but ran into problems 
with the software not being unsupported on 12.1-RELEASE (?).

I have not tried iocage.
