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). |

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