chrootuid - run command in restricted environment


chrootuid [-i] newroot newuser command...


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.


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.


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.


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