# This test verifies that the amazon-init service can treat the `user-data` ec2
|
|
# metadata file as a shell script. If amazon-init detects that `user-data` is a
|
|
# script (based on the presence of the shebang #! line) it executes it and
|
|
# exits.
|
|
# Note that other tests verify that amazon-init can treat user-data as a nixos
|
|
# configuration expression.
