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
  Exit with status 0 if the detection is not possible.
--help
  Print a usage message on standard output and exit successfully.
--version
  Print version information on standard output and exit successfully.

BUGS

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