NAME

injail —

determine if a process is running in a jail

SYNOPSIS

injail

DESCRIPTION

The injail utility returns a result which indicates the jailed status of the current process environment.

DIAGNOSTICS

The injail utility exits with one of the following values:

0: the process is running in a jail.
1: the process is not running in a jail.
2: an error prevented determining if the process is running in a jail.

BUGS

injail uses kvm_getprocs(3) to determine process status. Anything which could cause a failure in either kvm_open(3) or kvm_getprocs(3) can cause this to fail as well. There aught to be a cleaner way.
