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.
