## SHELL
Consul lock launches its children in a shell. By default, Consul will use the shell
defined in the environment variable `SHELL`. If `SHELL` is not defined, it will
default to `/bin/sh`. It should be noted that not all shells terminate child
processes when they receive `SIGTERM`. Under Ubuntu, `/bin/sh` is linked to `dash`,
which does **not** terminate its children. In order to ensure that child processes
are killed when the lock is lost, be sure to set the `SHELL` environment variable
appropriately.
