ischroot - detect if running in a chroot
ischroot [--default-false] [--default-true] [--help]
[--version]
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).
- -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.
On GNU/Linux, chroot detection is not possible when not root. This
works correctly on GNU/Hurd and GNU/kFreeBSD.
