updatejail - is a script for rebuilding a chrooted environment made
updatejail <config.file> <jail identifier>
updatejail is a script which wipes out a chroot environment and
rebuilds it. By default it leaves the /dev/log device in the chroot, so
you do not need to restart system logger after updating a jail.
Do not configure your daemon inside your jail, because updatejail
script will wipe out all the data inside the jail. If you would like to
change any setting inside the jail, make the changes in the original
location and then run updatejail . This makes it possible to place a
jail even to a ramdisk.
The configuration file which contains the settings of the new
chrooted environment. For further information see man 8
The identifier which specifies which jail will be used.
Identifiers need to be defined at jailer.conf . This identifier
has to match the directory name used in the Root location.
updatejail will not parse the configuration file and determine the Root
location by itself.
For updatejail to work the Root location for the jail identifier has to
end with the name of the identifier itself. For example, if your
identifier is apache the Root location in jailer.conf has to be
something like /chroots/apache.
