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.
