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.
