updatejail
JAILER(8) System Manager's Manual JAILER(8)
NAME
updatejail - is a script for rebuilding a chrooted environment made with jailer
SYNOPSIS
updatejail <config.file> <jail identifier>
DESCRIPTION
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.
WARNING
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.
Options
<config.file>
The configuration file which contains the settings of the new chrooted environment. For further information see man 8 jailer.conf
<jail identifier>
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.
BUGS
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.
