This chapter will provide an explanation of what FreeBSD jails are and how to use
them. Jails, sometimes referred to as an enhanced replacement of chroot environments, are a very powerful
tool for system administrators, but their basic usage can also be useful for advanced
users.
After reading this chapter, you will know:
-
What a jail is, and what purpose it may serve in FreeBSD installations.
-
How to build, start, and stop a jail.
-
The basics of jail administration, both from inside and outside the jail.
Other sources of useful information about jails are:
-
The jail(8) manual page.
This is the full reference of the jail utility -- the
administrative tool which can be used in FreeBSD to start, stop, and control FreeBSD
jails.
-
The mailing lists and their archives. The archives of the FreeBSD
general questions mailing list and other mailing lists hosted by the FreeBSD list server
already contain a wealth of material for jails. It should always be engaging to search
the archives, or post a new question to the freebsd-questions mailing list.
