Whether to enable emergency mode, which is an
|
|
{command}`sulogin` shell started on the console if
|
|
mounting a filesystem fails. Since some machines (like EC2
|
|
instances) have no console of any kind, emergency mode doesn't
|
|
make sense, and it's better to continue with the boot insofar
|
|
as possible.
