This package includes a special (but not thoroughly tested) pam module to provide chrooted (restricted) environments for users. the module tries to provide a transparent wrapper around the average user, one that puts them in a fake file-system (eg, their '/' is really /some/where/else).

in order to setup this environment in debian please read the readme.debian as well as the detailed example provided in /usr/share/doc/libpam-chroot/examples
