chrootuid

Simple wrapper that combines chroot(8) and su(1) into one program

The chrootuid command combines chroot(8) and su(1) into one program, so that there is no need to have commands such as /usr/bin/su in the restricted environment. Access to the file system is restricted to the newroot subtree and privileges are restricted to those of the newuser account (which must be a known account in the unrestricted environment).
