26. Jails
27. Since FreeBSD 4.X Subdirectory tree for jail Own hostname Own IP addresses Own users incl. root Complete separate FreeBSD in the Jail jail(8)
28. Port: sysutils/ezjail integrates ZFS # ezjail-admin install -spm # ezjail-admin create example.com '10.0.0.2' # ezjail-admin start example.com # ezjail-admin console example.com # ezjail-admin update -u ezjail
