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.
