NAME

       ischroot - detect if running in a chroot

SYNOPSIS

       ischroot [--default-false] [--default-true] [--help] [--version]

DESCRIPTION

       ischroot detects if it is currently running in a chroot. The exit status is:

       0      if currently running in a chroot

       1      if currently not running in a chroot

       2      if the detection is not possible (On GNU/Linux this happens if the script is not run as root).

OPTIONS

       -f, --default-false
	      Exit with status 1 if the detection is not possible.

       -t, --default-true

       --help Print a usage message on standard output and exit successfully.

       --version

BUGS

       On GNU/Linux, chroot detection is not possible when not root. This works correctly on GNU/Hurd and GNU/kFreeBSD.
