.TH JAILER 8 "December 4, 2001"
.SH NAME
updatejail \- is a script for rebuilding a chrooted environment made with jailer
.SH SYNOPSIS
updatejail <config.file> <jail identifier>
.SH DESCRIPTION

.I 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.

.SH WARNING

Do not configure your daemon inside your jail, because
.I 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
.I updatejail
\&. This makes it possible to place a jail even to a ramdisk.

.SH Options

.TP
.B <config.file>
The configuration file which contains the settings of the new chrooted
environment.  For further information see
.I man 8 jailer.conf

.TP
.B <jail identifier>
The identifier which specifies which jail will be used. Identifiers need
to be defined at
.I jailer.conf
\&. This identifier has to match the directory name used in the Root location.

.SH BUGS
.I updatejail
will not parse the configuration file and determine the Root location by itself.

For 
.I 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 \fBapache\fR the Root
location  in \fIjailer.conf\fR has to be something like \fB/chroots/apache\fR.
