.TH ISCHROOT 1 "30 May 2011" "Debian"
.SH NAME
ischroot \- detect if running in a chroot
.SH SYNOPSIS
.B ischroot
[\-\-default\-false] [\-\-default\-true] [\-\-help] [\-\-version]
.SH DESCRIPTION
.PP
.B ischroot
detects if it is currently running in a chroot. The exit status is:
.TP
0
if currently running in a chroot
.TP
1
if currently not running in a chroot
.TP
2
if the detection is not possible (On GNU/Linux this happens if the
script is not run as root).
.SH OPTIONS
.TP

Exit with status 1 if the detection is not possible.
.TP

Exit with status 0 if the detection is not possible.

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