NAME

       chrootuid - run command in restricted environment

SYNOPSIS

       chrootuid [-i] newroot newuser command...

DESCRIPTION

       The  chrootuid  command sets up a restricted environment for executing command. Access to the file system
       is restricted to the newroot subtree; privileges are restricted to those of the  newuser  account  (which
       must  be  a  known account in the unrestricted environment).  The initial working directory is changed to
       newroot.

       chrootuid 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.

       Only the superuser can use the chrootuid command.

OPTIONS

       There  is only one option for chrootuid: -i. That option makes it run in interactive mode. Errors will be
       printed on stderr instead of through syslog and the exit status will be 1 if there are any errors.

RETURN CODES

       The exit status of chrootuid when running on daemon mode (default) is always 0.

       If it is running on interactive mode, it will exit with an exit status of 1 if there is any error in  its
       invocation, otherwise the exit status is the exit status of command.

DIAGNOSTICS

       Problems  are  reported  to the syslog daemon if running on daemon mode.  If running on interactive mode,
       errors are reported on stderr.
