This includes a couple modifications to the cloud-init behavior.
First, the cloud-init wait action will now write a sentinel file
after successfully waiting for cloud-init. This results in subsequent
boots of the machine to skip executing the cloud-init wait command
as cloud-init is only executed on the initial boot.
Second, the cloud-init setup action will check for the sentinel file
written by the cloud-init wait action, and if detected it will skip
the cloud-init setup. When creating the ISO for cloud-init, a second
sentinel file will be used to log the path of the generated ISO
file. If the file exists, the ISO generation process will be skipped.
Adds two new options to the SSH connect configuration: `connect_retries`
and `connect_retry_delay`. Provides user configurable values used when
establishing the SSH connection. Previous behavior would retry generally
by the default value without a pause between attempts. Updated behavior
will retry the number of times set within the config (unless value is
provided directly to connect call) and each retry will pause based on
the delay value set in the config (unless value is provided directly
to the connect call).
Adds a new `key_type` option to the Vagrantfile ssh configuration. It
defaults to :auto which allows auto detection of key type to use.
Otherwise it can be set to an explicit type supported by Vagrant.
When performing a request via curl on Windows using schannel, ssl
certificate revocation checks does not handle verification failures
gracefully when an error is encountered that is unrelated to the actual
revocation of a certificate.
A new option is available to perform best effort revocation checks on
curl, so this is enabled by default on the Windows platform. A new
config option (`box_download_disable_ssl_revoke_best_effort`) has also
been added which can be optionally enabled to restore previous behavior
which results in a hard error if any error is encountered.
Recent versions of OpenSSH remove support of ssh-rsa key types and host
key algorithms from the default conection configuration. Set options to
enable them and provide a configuration option which can disable them if
required.
